Article Citation - WoS: 1Citation - Scopus: 1Triple Positive Solutions of M-Point Boundary Value Problem on Time Scales With P-Laplacian(Iranian Mathematical Soc, 2017) Dogan, A.In this paper, we consider the multipoint boundary value problem for one-dimensional p-Laplacian dynamic equation on time scales. We prove the existence at least three positive solutions of the boundary value problem by using the Avery and Peterson fixed point theorem. The interesting point is that the non-linear term f involves a first-order derivative explicitly. Our results are new for the special cases of difference equations and differential equations as well as in the general time scale setting.Article Citation - WoS: 2Citation - Scopus: 7Triple Positive Solutions for M-Point Boundary-Value Problems of Dynamic Equations on Time Scales With P-Laplacian(Texas State Univ, 2015) Dogan, AbdulkadirIn this article we study the existence of positive solutions for m-point dynamic equation on time scales with p-Laplacian. We prove that the boundary-value problem has at least three positive solutions by applying the five functionals fixed-point theorem. An example demonstrates the main results.Article Citation - WoS: 10Citation - Scopus: 12Positive Solutions of the P-Laplacian Dynamic Equations on Time Scales With Sign Changing Nonlinearity(Texas State Univ, 2018) Dogan, AbdulkadirThis article concerns the existence of positive solutions for p-Laplacian boundary value problem on time scales. By applying fixed point index we obtain the existence of solutions. Emphasis is put on the fact that the nonlinear term is allowed to change sign. An example illustrates our results.Article Citation - WoS: 7Citation - Scopus: 7Positive Solutions of Nonlinear Multi-Point Boundary Value Problems(Springer, 2018-05-17) Dogan, AbdulkadirThis paper deals with the existence of positive solutions of nonlinear differential equation subject to the boundary conditions By using Schauder's fixed point theorem, we show that it has at least one positive solution if f is nonnegative and continuous. Positive solutions of the above boundary value problem satisfy theHarnack inequality inf(0 <= t <= 1) u(t) >= gamma parallel to u parallel to(infinity.)Article Citation - WoS: 7Citation - Scopus: 9On the Existence of Positive Solutions of the P-Laplacian Dynamic Equations on Time Scales(Wiley, 2017-01-26) Dogan, AbdulkadirIn this paper, we investigate the existence of positive solutions for a nonlinear m-point boundary value problem for the p-Laplacian dynamic equations on time scales, by applying a Krasnosel'skii's fixed point theorem. As an application, an example is included to demonstrate themain results. Copyright (C) 2017 John Wiley & Sons, Ltd.Conference Object Citation - Scopus: 1On the Existence of Positive Solutions for the Time-Scale Dynamic Equations on Infinite Intervals(Springer, 2020) Doǧan, Abdülkadir MuhittinThis paper investigates the existence of positive solutions to time-scale boundary value problems on infinite intervals. By applying the Leggett-Williams fixed point theorem in a cone, some new results for the existence of at least three positive solutions of boundary value problems are found. With infinite intervals, the theorem can be used to prove the existence of solutions of boundary value problems for nonlinear dynamic equations dependence on the delta derivative explicitly. Our results are new for the special cases of difference equations and differential equations as well as in the general time scale setting. © 2020 Elsevier B.V., All rights reserved.Article Citation - WoS: 1Citation - Scopus: 10Existence of Three Positive Solutions for an M-Point Boundary-Value Problem on Time Scales(Texas State Univ, 2013) Dogan, AbdulkadirWe study an m-point boundary-value problem on times 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.Article Citation - WoS: 1Citation - Scopus: 10Existence of Countably Many Positive Solutions for Nonlinear Boundary Value Problems on Time Scales(Natural Sciences Publishing Corp-nsp, 2014-09-01) Dogan, AbdulkadirIn this paper, we consider the existence of countably many positive solutions for nonlinear singular boundary value problem on time scales. By using the fixed-point index theory and a new fixed-point theorem in cones, the sufficient conditions for the existence of countably many positive solutions are established.Article Citation - WoS: 1Citation - Scopus: 1Eigenvalue Problems for Singular Multi-Point Dynamic Equations on Time Scales(Texas State Univ, 2017) Dogan, AbdulkadirIn this article, we study a singular multi-point dynamic eigenvalue problem on time scales. We find existence of positive solutions by constructing the Green's function and studying its positivity eigenvalue intervals. Two examples are given to illustrate our results.
