Nos hablará sobre "Brownian web and net as universal scaling limits".

*Abstract:* The Brownian web is an infinite collection of 1d coalescing
Brownian paths starting from every space-time point $(x,t)\in \R^2$. The
Brownian net is obtained by adding an extra branching mechanism in the
picture (i.e., it is an infinite collection of coalescing-branching 1d
Brownian paths). In this talk, I will introduce a rigorous construction of
both continuum objects. I will also discuss how they emerge as the scaling
limits of various discrete models in the context of statistical mechanics
models and math biology. In particular, I will show how the Brownian net
relates to a class of random walks in random environment, which has been
recently shown to be connected to the KPZ universality class.
