Several existence theorems of positive solutions are established for nonlinearm-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=1m−2aiϕ(uΔ(ξi)),u(T)=∑i=1m−2biu(ξi), whereϕ:R→Ris an increasing homeomorphism and homomorphism andϕ(0)=0. As an application, an example to demonstrate our results is given.

In this paper, we study a general second-orderm-point boundary value problem for nonlinear singular dynamic equation on time scalesuΔ∇(t)+a(t)uΔ(t)+b(t)u(t)+λq(t)f(t,u(t))=0,t∈(0,1)𝕋,u(ρ(0))=0,u(σ(1))=∑i=1m-2αiu(ηi). This paper shows the existence of multiple positive solutions iffis semipositone and superlinear. The arguments are based upon fixed-point theorems in a cone.

Several existence theorems of twin positive solutions are established for a nonlinearm-point boundary value problem of third-orderp-Laplacian dynamic equations on time scales by using a fixed point theorem. We present two theorems and four corollaries which generalize the results of related literature. As an application, an example to demonstrate our results is given. The obtained conditions are different from some known results.

UDC 517.9 Розглядається триточкова крайова задача для динамiчного рiвняння iз p-лапласiаном на часових шкалах. За допомогою теореми Ейвери та Петерсона про нерухому точку доведено iснування принаймнi трьох додатних розв’язкiв такої крайової задачi. Умови, якi використовуються тут, вiдрiзняються вiд умов, якi використано у бiльшостi вiдомих нам робiт. Цiкавим моментом є те, що нелiнiйний член f мiстить першу похiдну невiдомої функцiї. Як застосування наведено приклад для iлюстрацiї отриманих результатiв.
