非线性项变号的非局部边值问题正解的存在性
Existence of Positive Solutions for a Nonlocal Boundary Value Problem with Sign Changing Nonlinearities
【摘要】 研究了非线性项变号的非局部边值问题正解的存在性,应用Nowhere normal-outward紧映射的不动点指数理论,在f(t,0)≥0且满足次线性条件下,得到边值问题正解的存在性结论.
【Abstract】 The nonlocal boundary value problems with nonlinearities changing signs are studied,the existence of positive solutions is obtained by using the Nowhere normal-outward compact map’s fixed point index theorem under f( t,0) ≥0 and sub-linear conditions.
