一类奇异非线性四阶两点边值问题的正解

Positive solutions to a class of singular nonlinear fourth order two point boundary value problem

利用不动点指数理论对一类奇异超线性或次线性四阶边值问题建立了正解的存在性定理,推广了已有的结果.

In this paper, we establish the existence theorem of positive to a class of singular for suplinearity or fourth order sublinearity fourth order boundary value problem, by using the fixed point index theorem in cones. Our results essentially generalized the theorem in the previous papers.
