摘要:

考虑如下问题

u=uN+2/N-2+∈f(x)u,   x∈RN
 uD1,2(RN), u(x)→0, |x|→∞,
这里ε是正常数, f(x)∈L(RN), N为大于3的正整数. 该文应用扰动方法证明了在f(x)适合一定条件下, 存在ε0, 只要0<ε<ε0, 上述问题存在多个解.

关键词: 半线性, 临界增长, 椭圆型, 多解

Abstract:

In this paper, we consider the following problem
   -Δu=uN+2/N-2+∈f(x)u,   x∈RN
   uD1,2(RN), u(x)→0, |x|→∞,
where ∈ is a positive constant, f(x)∈L(RN), N>3. Used perturbation method, we prove that under some conditions on f(x), there exists a ∈0, if 0<ε<ε0, such that there are many solutions for above problem.

Key words: Semilinear, Sobolev exponent, Elliptic, Multiple solutions
