A Generalized Rough Super Brownian Motion

Abstract: In this paper, we construct scaling limits of some branching random walks in random environment whose off-spring distributions have infinite variance. The Laplace functional of the obtained random measure is given by a non-linear PAM, whose existence and uniqueness are also proved as an intermediate step. We also give a martingale characterization of above super-process and show that it possesses the compact support property and exponential persisitency.
