奇异(n-1,1)共轭边值问题的多解性

Multiple-positive Solutions of Singular (n-1,1)Conjugate Boundary Value Problems

本文在非线性项f（u）呈S－型的前提下，讨论了奇异非线性（n—1，1）共轭边值问题多个正解的存在性，所用工具为锥拉伸与锥压缩不动点定理．

This paper study the existence of multiple-positive olutions of nonlinear singular (n-1, 1 )conjugate B. V. P. under the condition that f shows s--model. The tool we used is conepull and cone-compress theorem.
