摘 要:
利用变分法和一个三临界点定理,证明了一类拟线性椭圆方程{-div(α|△↓u^·|^p)|△↓u|^p-2△↓u)=λf(x,u),Ω,u=0,δΩ在某些新的条件下至少存在三个解,其中Ω∪→R^n(n≥1)是一个具有光滑边界的有界区域,且α∈C(R^+,R),p〉n,λ〉0为一实参数.并给出了该结论在毛细现象中的广义Capillarity方程的一个应用.[著者文摘]

Abstract:
Using variational methods and a three critical points theorem, the existence of at least three weak solutions for the following quasilinear elliptic equation is studied under some novel conditions.{-div(α|△↓u^·|^p)|△↓u|^p-2△↓u)=λf(x,u),Ω,u=0,δΩ,Where Ω∪→R^n(n≥1)is a bounded domain with smooth boundary,λ〉0 is a real parameter,p is real number larger than n.As the application of main theorem,an example about Capillarity equation is obtained.[著者文摘]
