Existence theory for single and multiple solutions to semipositonediscrete Dirichlet boundary value problems with singular dependent nonlinearities

[摘要] In this paper we establish the existence of single and multiple solutions to the semipositone discrete Dirichlet boundary value problem{Δ2y(i−1)+μf(i,y(i))=0,            i∈{1,2,…,T}y(0)=y(T+1)=0,whereμ>0is a constant and our nonlinear termf(i,u)may be singular atu=0.
