      We describe a model for information or viral transmission on the complete graph $\mathbb{K}_n$.
      Each node is an individual which may be susceptible, infected or recovered.
      This model has been introduced by Comets et al. with the main goal of studying the asymptotic behavior, as $n$ goes to infinity, of the duration of the infection and of the proportion of infected individuals in the population.
      The results rely on two interesting stochastic processes: the GW process and the coupon collector process.
      We discuss some extensions of this problem

    • Abstract
      The aim of this talk is to connect utiility maximization problems and the optimization of dynamic
      risk measures, which are usually considered as two different branches or approaches to financial
      problems.
      A reinsurance contract allows an insurance company to transfer part of the risk to another company,
      namely the reinsurer, in order to reduce the future losses, which are usually modeled as a marked
      point process. Finding the optimal reinsurance agreement translates into a stochastic control
      problem for the insurer. Recently, some authors showed that the optimal value process for the utility
      maximization problem can be characterized as the solution of a BSDE with jumps. In
      other works, it is proved that some BSDEs induce dynamic risk measures, which can be financially
      interpreted as a default time and an associated mark. In this talk we aim to explore the properties of
      the risk measure induced by the optimal reinsurance policy under dierent risk models with jumps.
      The talk is based on a work in progress with Fulvia Confortola (Politecnico of Milan).

    • Abstract
      In this talk I will discuss some results concerning geometric flows. In particular, we will focus on flows with a volume constraint and whose motion is depending on their mean curvature, which (formally) arise as gradient flows for the perimeter functional.
      After an introduction on the topic, aimed at a general audience, we will discuss a novel geometric inequality, which takes the form of a quantitative Alexandrov theorem, in the periodic setting. We will then show how to use this inequality to prove global existence and to characterize the asymptotic behaviour for some instances of volume-preserving geometric flows. Our results apply to the volume-preserving mean curvature flow, the surface diffusion flow and the Mullins-Sekerka flow.
      This work is based on a collaboration with Anna Kubin (TU Wien), Andra Kubin (University of Jyväskylä) and Antonia Diana (Sapienza University).

    • Abstract
      Feynman-Kac formulas provide probabilistic representations of the semigroup generated by a selfadjoint operator, i.e., the solution of the corresponding heat equation. We first review this concept in the traditional setting for Schrödinger-type operators. Then, we discuss how to derive Feynman-Kac formulas for a class of models with operator-valued potentials, describing a non-relativistic particle linearly coupled to a bosonic quantum field. This class contains ultraviolet regularized versions of well-known models like the spin boson model, the Fröhlich polaron and the Nelson model.

      We then discuss how to remove the ultraviolet regularization, by an application of stochastic calculus. If time allows, we present some recent applications of the so-obtained formulas. The talk is based on joint works with Daniel Fröhlich, Fumio Hiroshima and Oliver Matte.

The condition \(\text{Ric}_2 > 0\) is an intermediate curvature condition that interpolates between positive sectional curvature (\(\text{sec}> 0\)) and positive Ricci curvature (\(\text{Ric}> 0\)). We achieve this using a generalization of the fat bundle notion.

    • Machine learning (ML) has emerged as a critical tool in contemporary climate research. This workshop will explore prospects for ML tools to enhance the design and assessment of medium- and long-term scenarios of greenhouse gas emissions. We will cover some of the latest applications, from the use of ML in the development of integrated assessment models (IAMs) of climate change to the opportunities of ML to assist the construction and evaluation of large ensembles of emission scenarios. Due to the specific nature of ML tools, the workshop will also be an occasion to reflect on emerging issues of opacity and the potential challenges in the implementation of ML in influential exercises of climate policy evaluation, such as those of the IPCC. Specifically, the workshop will address the following questions: - DATA ENHANCEMENT: Can ML tools help streamline the collection and curation of data to feed the models (IAMs) that produce emission scenarios? - MODEL ENHANCEMENT: Can neural networks and equations discovery tools integrate standard numerical modeling approaches to help re-design IAMs? - POST-PROCESSING: Can ML emulators be used to detect bias and infill missing dimensions of uncertainty in large ensembles of emission scenarios? - ASSESSMENT: What consequences can the use of ML tools have on the informativeness and trustworthiness of assessments of large scenario ensembles? We look forward to the participation of engineers, mathematicians, and other researchers with an expertise in ML. One of the workshop’s aims is to build further capacity to assist climate research and explore connections across emerging fields of research. The workshop will be held in Aula FDS, IV Floor, Department of Mathematics, Politecnico di Milano. Participation is free of charge. Registration is not required. Contact: francesco.nappo@polimi.it

    • Abstract
      Structurally, brain tissue is characterized by thin cell membranes and slender vessels, defining submanifolds of codimension one and two respectively.  Functionally, your brain fundamentally relies on the transport of ions and nutrients and movement of water in and between these spaces. These physiological processes are clearly crucial for brain function and health, but the precise mechanisms and their association with neurodegenerative diseases such as Alzheimer's and Parkinson's disease and neurological events such as seizures remain only partially understood. Notably, mathematical and computational modelling are beginning to play an important role in gaining new insight. In this talk, I will discuss key mathematical, numerical and computational challenges associated with modelling brain mechanics and transport across scales with an emphasis on coupled systems of partial differential equations with dimensional gaps.

    • Abstract
      In this talk, geometric numerical integration meets stochastic numerics. In particular, the attention is focused on recent advances regarding the numerical preservation of qualitative/quantitative aspects and invariance laws characterizing the dynamics of various stochastic ordinary and partial differential equations. The talk moves towards the following two tracks:

      -geometric numerical integration of stochastic Hamiltonian problems. For these problems, two different scenarios are clarified: if the noise is driven in the Ito sense, the expected Hamiltonian function exhibits a linear drift in time; in the Stratonovich case, the Hamiltonian is pathwise preserved. In both cases, the talk aims to highlight the attitude of selected numerical methods in preserving the aforementioned behaviors. A long-term investigation via backward error analysis is also presented;

      -structure-preserving numerics of dissipative problems. The investigation moves towards the numerical conservation of mean-square contractivity in the time integration of dissipative problems, via stochastic theta-methods. The analysis shows that numerical contractivity in mean-square sense is hidden within proper stepsize restrictions.

      A general guideline is given by the assessment of a bridge between numerical modelling of stochastic problems and that for the underlying deterministic ones. This talk is based on the joint research in collaboration with Chuchu Chen (Chinese Academy of Sciences), David Cohen (Chalmers University of Technology & University of Gothenburg), Stefano Di Giovacchino (University of L’Aquila), and Annika Lang (Chalmers University of Technology & University of Gothenburg).

    • Abstract
      Scientific machine learning (SciML) has been taking the academic world by storm as an interesting blend of traditional scientific modeling with machine learning (ML) methodologies like deep learning. While traditional machine learning methodologies have difficulties with scientific issues like interpretability, and enforcing physical constraints, the blend of ML with numerical analysis and differential equations has evolved into a novel field of research which overcome these problems while adding the data-driven automatic learning features of modern machine learning. Many successes have already been demonstrated, with tools like physics-informed neural networks, universal differential equations, deep backward stochastic differential equation solvers for high dimensional partial differential equations, and neural surrogates showcasing how deep learning can greatly improve scientific modeling practice. Consequently, SciML holds promise for versatile application across a wide spectrum of scientific disciplines, ranging from the investigation of subatomic particles to the comprehension of macroscopic systems like economies and climates.
      However, despite notable strides in enhancing the speed and accuracy of these methodologies, their utility in practical and specifically industrial settings remain constrained. Many domains within the scientific community still lack comprehensive validation and robustness testing of SciML approaches. This limitation is particularly pronounced when confronted with complex, real-world datasets emanating from interactions between machinery and environmental sensors as usually addressed in industry. Still if appropriately addressed, SciML with its promise to accelerate innovations and scientific discoveries by orders of magnitudes, offers unique opportunities to address the insatiable desire for faster and more accurate predictions in many fields.
      This presentation is dedicated to exploring recent advancements in the implementation of SciML techniques. We will discuss how methodologies can be refined to ensure their practical viability and scalability, particularly in industrial sectors where digital and physical components converge.

    • Abstract
      In recent decades, the theory of optimal transport has advanced rapidly, finding an ever-growing range of applications. The original problem of Monge is to find the cheapest way to transform one probability distribution into another when the cost is proportional to the distance. The most important metric structure that is related to optimal transport is the so-called p-Wasserstein space [denoted by Wp(X)] over the metric space X.

      The pioneering work of Bertrand and Kloeckner started to explore fundamental geometric features of 2-Wasserstein spaces, including the description of complete geodesics and geodesic rays, determining their different types of ranks, and understanding the structure of their isometry group.

      In this talk I will focus on isometry groups. A notable and useful property of p-Wasserstein spaces is that X embeds isometrically into Wp(X), moreover an isometry of X induces an isometry of Wp(X) by the push-forward operation. These induced isometries are called trivial isometries, and we say that Wp(X) is isometrically rigid if all its isometries are trivial. The question is: are there non-rigid Wasserstein spaces? What does a non-trivial isometry look like? Until very recently, only a few non-rigid examples were known such as the 2-Wasserstein space over R^n, and the 1-Wasserstein space over [0,1].

      In the first part of the talk, I will introduce some key concepts and notation. The main focus will then shift to exploring results concerning both rigidity and non-rigidity in Wasserstein spaces.

    • The goal of this workshop is to gather researchers working in the field of Partial Differential Equations with expertise in nonlocal and nonlinear equations. Among others, one of the simplest mathematical ways to describe many real-world problems is to start from a set of interacting particles, resulting in nonlocal and nonlinear PDEs in the many-particle limit. Despite the past progress in this field, recent discoveries in biology, plasma physics, and data science, among others, shed the lights on new challenges involving nonlocal structures, such as networks or graphs, and highly nonlinear and singular aggregation-diffusion equations. During the workshop we will focus on various mathematical issues in this direction, for instance: micro-macro description of diffusion process, evolutions on graphs, fluxes with nonlinear mobility, fourth-order aggregation-diffusion equations, etc. This workshop is partially funded by the Advanced Grant Nonlocal-CPD: "Nonlocal PDEs for Complex Particle Dynamics: Phase Transitions, Patterns and Synchronization" of the European Research Council Executive Agency (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No. 883363).
