摘要 运用锥上的不动点定理,讨论时间模上的二阶非线性动力学方程m-点边值问题多个正解的存在性.其中T是一个时间模,ξi∈(0,T)T,0<ξ1<ξ2<…<ξm-2<T,αi,bi 0,0<∑i=1αi<1,0<∑m-2bi<1. By using fixed point theorems in cones, we study the existence of at least three positive solutions of a nonlinear second-order m-point boundary value problem for dynamic equations on time scales.
