A NOTE ON DIRICHLET PROBLEM FOR SEMILINEAR SECOND ORDER ELLIPTIC EQUATION |
AO En,ZHANG Guo-wei

Abstract: |
In this paper, we study the Dirichlet problem for semilinear second order elliptic equation. By using the mountain pass lemma and the least action principle, we obtain the existence of weak solution to semilinear second order elliptic equation under some new conditions which are different from the previous ones. |
