Title：V-shaped fronts around an obstacle

Time：10:30 a.m.，Dec. 12, 2019

Location：Qiyun building, Room911

Abstract:In this talk, I will talk about V-shaped fronts around an obstacle K. I will show that there exist solutions emanating from any homogeneous transition front including V -shaped front for exterior domains R^N\K. By providing the complete propagation of the V-shaped front, I will show that the V -shaped front can recover after passing the obstacle.impulsive interventions.
