Abstract

Several existence theorems of positive solutions are established for nonlinear m-point boundary value problem for the following dynamic equations on time scales (ϕ(uΔ))+a(t)f(t,u(t))=0, t(0,T), ϕ(uΔ(0))=i=1m2aiϕ(uΔ(ξi)), u(T)=i=1m2biu(ξi), where ϕ:RR is an increasing homeomorphism and homomorphism and ϕ(0)=0. As an application, an example to demonstrate our results is given.
