Abstract
In this paper, we study the classical solutions of the fully nonlinear parabolic equation \({u_{t}-F(D_{x}^2u)=0,}\) where the nonlinear operator F is locally C 1,β almost everywhere with 0 < β < 1. The interior C 2,α regularity of the classical solutions will be shown without the assumption that F is convex (or concave).
