该文研究了p-Laplacian动力边值问题(g(u^△(t)))△+a(t)f(t,u(t))=0,t∈[0,T]T,u(0)=u(T)=w,u△(0)=-u^△(T)正解的存在性.其中W是非负实数,g(v)=|v|p-2v1 P>1.根据对称技巧和五泛函不动点定理,证明了边值问题至少有三个正的对称解,同时,给出了一个例子验证了我们的结果。
This paper is concerned with the p-Laplacian boundary value problem (g(u^△(t)))△+a(t)f(t,u(t))=0,for t∈[0,T]T,u(0)=u(T)=w,u△(0)=-u^△(T), where w is a nonnegative real number and g(v)= |v|p-2 v with p 〉 1. By using symmetry technique and a five functionals fixed-point theorem, we prove that the boundary value problem has at least three positive symmetric solutions. As application, an example is given to illustrate our result.
