W01,p中二阶拟线性椭圆型障碍问题解的存在性
The Existence of Solution for Second Order Quasilinear Obstacle Problem in W01,p
【摘要】 本文应用临界点理论,讨论如下的拟线性障碍问题A,求,使得其中K={v∈W01,p(Ω)v≥ψa.e.于Ω}.在一定的假设下,得到了广义解的存在性,并给出了ψ=0时问题之解的Pohozcav恒等式,进而得到解之不存在性的“结构条件”.
【Abstract】 In this paper, the following quasilincar obstacle problem A: find u∈K such that ∫_Ω F (x, u, Du)·D_i(u-v)dx where. is discussed via critical theory. Under some hypotheses, the existence and pohozeav identity of the solutions are obtained, and the structure condition of noncxistcncc of the solutions is derived.
