摘 要：

Nonlocal diffusion is introduced to describe the movement or interaction of some organisms between non-adjacent spatial locations. In this talk, we study the nonlocal version of the classical Stefan problem. We first demonstrate the wellposedness and the convergence between nonlocal Stefan problem and classical Stefan problem. Next, we construct some examples to demonstrate some new phenomena due to the appearance of nonlocal diffusion, like the discontinuous movement of population range. At the end, the spreading/vanishing phenomena is discussed when reaction term is introduced. This is joint work with Xinfu Chen and Maolin Zhou.
