On KPZ problem and statistics of stochastic flows

In this talk we will discuss a geometrical approach to the problem of the KPZ Universality.
Instead of looking at the height (interface) function and Airy processes, we will focus on the statistics
of shocks and points of concentration of mass. We will also discuss the connection with the problem
of the coalescing Brownian motions and coalescing fractional Brownian motions.
