报告内容简介：

Traveling wave solution of a bistable equation is well understood when the nonlinearity is smooth. In this talk we will consider a case that the nonlinearity has has a discontinuity at zero. This discontinuity may give us interesting phenomenon such as finite time extinction, Allee effect, or free boundary.
