一维p-Laplace边值问题正解的存在唯一性
Existence and Uniqueness of Positive Solutions for One-dimensional p-Laplac
【摘要】 利用积分方法讨论p-Laplace边值问题(|y’|p-2y’)’+f(y)=0,y(-b)=y(b)=0正解的存在唯一性,其中f是取正值的连续函数,并且f(y)/yp-1关于变元y是单调递减的.
【Abstract】 In this article we use the quadrature method to discuss the existence and uniqueness of the positive solutions of the boundary value problem(|y’|p-2y’)’+f(y)=0,y(-b)=y(b)=0.Assume that f is continuous and positive on(0,+∞),and f(y)/yp-1 is nonincreasing.
