摘要 研究一类具Laplacian算子的m点边值问题(Ф(u'))'+q(t)f(t,u)=0,0〈t〈1,u(0)=^m-2∑i=1aiu(ζi),u'(1)=βu'(0).利用锥上的不动点指数定理,对上述具有变号的非线性项的边值问题进行研究,得到多个正解存在的充分条件. In this paper, for the m-point boundary value problem with p-Laplacian operator (Ф(u'))'+q(t)f(t,u)=0,0〈t〈1,u(0)=^m-2∑i=1aiu(ζi),u'(1)=βu'(0).By using the fixed point index theorems on cone, we consider the m-point boundary value problem with sign changing nonlinear term, and sufficient conditions for the existence of multiple positive solutions are obtained.
