index theorem meaning in Chinese

指数定理

This paper discusses the existence of multiple positive solutions of a class of nonlinear singular boundary value problems by means of the fixed point index theorem on cones
摘要利用锥映射的不动点指数定理，研究了一类非线性奇异边值问题多个正解的存在性问题。
By using the fixed point index theorem , the existence of positive solutions for nonlinear m - point boundary value problem is established under some weaker conditions , and previous results are improved and generalized
摘要本文在较弱的条件下，利用不动点指数定理研究了一类算子多点边值问题正解的存在性，推广并改进了原有的结果。
