研究了帶源項的非線性拋物方程Cauchy問題解存在的必要條件以及解所應(yīng)具有的性質(zhì),通過把文獻(xiàn)中的線性算子推廣到形式較一般的帶源項的非線性拋物算子,利用其中處理線性問題的方法來處理非線性問題.

The existence conditions of solutions of a class of nonlinear parabolic equation

This paper discusses the necessary conditions of solution to a class of nonlinear parabolic equation and the nature of the solution.By extending the linear operator to a more general form of nonlinear parabolic operator with the source term,we use the method in document which was used to handle the linear problem to handle the nonlinear problem.
