Title：A lower spatially Lipschitz bound for solutions to fully nonlinear parabolic equations and its optimality
Abstract：We derive a lower spatially Lipschitz bound for viscosity solutions to fully nonlinear parabolic partial differential equations when the initial datum is singular but belongs to the Hölder space. Our estimate gives the optimal rate of Lipschitz regularizing effects for solutions, which occur for some uniformly parabolic equations and first order Hamilton-Jacobi equations.
