摘要
运用凸集上的临界点理论和Ekeland变分原理,通过研究W_o^(1,p)(Ω)上的泛函??相对于W_o^(1,p)(Ω)的闭凸子集K的临界点,证明了二阶变分不等式??的三解存在性定理.
In order to study the solution of the variational inequality
??
We seek the critical points of the functional
??
on the closed convex set K of W_o^(1,p)(Ω), and prove a three-solution theorem by the critical point theory and the Ekeland variational principle.
