Abstract:This paper sets up the fixed point theorems for cone stretching or compression and more extensive fixed point theorems for cone stretching or compression in their normal forms on the condensing mapping. At the same time, we get corresponding results for noncone mapping in their normal forms. Furthermore,we utilize our results to study the global characteristics of the eigenvalue on the condensing operator and the nonzero solution of operator equation, and application to YpbIcoH operator. Finally, this paper studies the nonzero solution for a class of nonlinear integral equations, and obtains better new results.
Keywords:condensing mapping  partial order  cone stretching or compression  fixed point  eigenvalue  global characteristics  nonzero solution
