摘要:

This article considers the equation
2 u =f(x,u)
with boundary conditions either u|Ω=un|Ω=0 or u|Ω=△u|Ω=0, where f(x,t) is asymptotically linear with respect to t at infinity, and Ω is a smooth bounded domain in RN, N >4. By a variant version of Mountain Pass Theorem, it is proved that the above problems have a nontrivial solution under suitable assumptions of f(x,t).
