TITLE: A weak universality result for the parabolic Anderson model

ABSTRACT: We consider a class of nonlinear population models on a
two-dimensional lattice which are influenced by a small random
potential, and we show that on large temporal and spatial scales the
population density is well described by the continuous parabolic
Anderson model, a linear but singular stochastic PDE. The proof is based
on a discrete formulation of paracontrolled distributions on unbounded
lattices which is of independent interest because it can be applied to
prove the convergence of a wide range of lattice models. This is joint
work with Jörg Martin.
