RT Journal Article T1 Uniqueness and collapse of solution for a mathematical model with nonlocal terms arising in glaciology A1 Tello del Castillo, José Ignacio A1 Muñoz, Ana Isabel AB In this paper we study a nonlinear system of differential equations which arises from a stationary two-dimensional Ice-Sheet Model describing the ice-streaming phenomenon. The system consists of a multivalued nonlinear PDE of parabolic type coupled with a first-order PDE and an ODE involving a nonlocal term. We study the uniqueness of weak solution under suitable assumptions (physically reasonable). We also establish that the ice thickness collapses at a finite distance (by employing a comparison principle).
