## Higher order boundary value problems on time scales.(English)Zbl 1124.34009

This paper deals with the existence of positive solutions to the Lidstone boundary value problem $(-1)^n y^{\Delta^{2n}}(t) = f(t, y(\sigma(t))), \quad t \in [0,1],$
$y^{\Delta^{2i}}(0) = y^{\Delta^{2i}}(\sigma(1)) = 0, \quad 0 \leq i \leq n-1,$ where $$n \geq 1$$ and $$f: [0,\sigma(1)] \times \mathbb{R} \to \mathbb{R}$$ is continuous. The problem is considered on a time scale with the right-dense $$\sigma(1)$$. The paper develops as follows.
The introductory Section 1 provides an overview of related recent results and estimates on the Green function associated with the problem. Section 2 contains an existence result under the assumption of a bounded inhomogeneous term, which follows from the Schauder fixed point theorem. Another existence result is based on the assumption that lower and upper solutions $$u$$, $$v$$ exist and are in the well order, that is, $$u \leq v$$. Sections 3 is devoted to the existence of a positive solutions. The assumptions made here are the sub- and super-linearity of $$f \geq 0$$. The results of the last section follow from the Krasnosel’skiĭ fixed point theorem of cone compression-expansion type.
