摘要: 考虑如下带有Dirichlet边值条件的半线性椭圆方程: -Δu = f (x ,u) x ∈Ω u =0 x ∈?Ω 在非线性项 f满足广义次临界及其他条件时,通过Morse理论和局部环绕定理得到方程有两个非平凡解的结论。

Abstract: The following semilinear elliptic equations with Dirichlet boundary value conditions - Δu = f (x ,u) x ∈ Ω u = 0 x ∈ ?Ω has been studied in this paper .Under certain assumptions on nonlinear f with more general subcritical grow th conditions ,some new multiplicity results of nontrivial solutions are established via morse theory and local linking . -
