Title: Existence of positive solutions for p-Laplacian three-point boundary-value problems on time scales Authors: Hong-Rui Sun (Lanzhou Univ., Gansu, China) Ying-Hai Wang (Lanzhou Univ., Gansu, China) Abstract: This article shows the existence of positive solutions for a class of p-Laplacian three-point boundary-value problem on time scales. By using several fixed point theorems in cones, we establish conditions for the existence of at least one, two or three positive solutions for the boundary-value problems. Our results are new even for the corresponding differential ($\mathbb{T}=\mathbb{R})$ and difference equation ($\mathbb{T}=\mathbb{Z})$, and for the general time scales setting. An example is also given to illustrate our results. Submitted January 26, 2007. Published July 02, 2008. Math Subject Classifications: 34B15, 39A10.
