Quasiconvexity preserving property for fully nonlinear nonlocal parabolic equations
In this talk, we discuss the quasiconvexity preserving property of positive viscosity solutions to a class of fully nonlinear parabolic equations with monotone nonlocal terms. We prove that if the initial value is quasiconvex, the viscosity solution to the Cauchy problem stays quasiconvex in space for all time. Our proof can be regarded as a limit version of the arguments for power convexity preservation as the exponent tends to infinity. We also present several concrete examples to show applications of our result.
This talk is based on joint work with Takashi Kagaya (Muroran Institute of Technology) and Hiroyoshi Mitake (University of Tokyo).
