Abstract

We discuss the existence of global classical solution for the uniformly parabolic equation

$$\left\{ \begin{gathered} u_t = a(x,t,u,u_x ,u_{xx} ) + b(x,t,u,u_x ), (x,t) \in ( - 1,1) \times (0,T], \hfill \\ u( \pm 1,t) = 0, u(x,0) = \varphi (x), \hfill \\ \end{gathered} \right.$$

Wherea is strongly nonlinear with respect tou xx and ϕ is not necessarily small. We also deal with nonuniform case.
