Title: Existence of three positive solutions for an m-point boundary-value problem on time scales Authors: Abdulkadir Dogan (Abdullah Gul Univ., Kayseri, Turkey) Abstract: We study an m-point boundary-value problem on time scales. By using a fixed point theorem, we prove the existence of at least three positive solutions, under suitable growth conditions imposed on the nonlinear term. An example is given to illustrate our results. Submitted March 29, 2013. Published June 27, 2013. Math Subject Classifications: 34B15, 34B16, 34B18, 39A10.
