摘要:

文中考虑了下面带奇异项的双调和方程

{?2u-μ/|x|α μ λg(x)μ+k(x)|μ|q-2 μ+|μ|2*-2 μ,      x ∈ Ω,  
  μ ∈D02,2(Ω),                                                        x ∈∂Ω,

其中0 ∈Ω为RN, N ≥ 5中的有界区域,  0 ≤ α, s < 4,2 < q < 2*(s) = 2(N-s)/N-4}, g(x), k(x) 为非负函数, 借助变分方法及嵌入映射D2,2(RN) → L2*(RN)的达到函数, 通过较精密的计算, 得到了上面方程解的存在性结果.

Abstract:

In this paper, the authors present a result on existence to the following singular biharmonic equation involving
singular terms
{?2u-μ/|x|α μ λg(x)μ+k(x)|μ|q-2 μ+|μ|2*-2 μ,      x ∈ Ω,  
  μ ∈D02,2(Ω),                                                        x ∈∂Ω,

where Ω is a bounded domain containing origin, Ω ( RN, N ≥ 5, 0 ≤ α, s < 4,2 < q < 2^*(s) = 2(N-s)/N-4}, and g(x), k(x) are nonnegative functions, the existence of solution is shown by variational method, the acquired function for the imbedding mapping D2,2(RN) → L2*(RN) plays an important role in the discussion.

Key words: Critical exponent, Variational method, Singular
