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: 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 - Scopus: 3Existence of Positive Solutions for P-Laplacian an M-Point Boundary Value Problem Involving the Derivative on Time Scales(Texas State Univ, 2014) Dogan, AbdulkadirWe are interested in the existence of positive solutions for the p-Laplacian dynamic equation on time scales (phi(P)(u(Delta)(t)))(V) a(t)f (t, u Delta(t), (t)) = 0, t is an element of (0,T)(T), subject to the multipoint boundary condition, u(0) = Sigma(m-2)(i=1) alpha iu, (xi(i)) = u Delta(T) = 0, where phi(p)(S) = vertical bar s vertical bar p(-2) s, p > 1, xi i is an element of [0, T](T,) 0 < xi 1 < xi 2 < . . . < xi m-2 < p(T). By using fixed point theorems, we prove the existence of at least three nonnegatvie solutions, two of them positive, to the above boundary value problem. The interesting point is the nonlinear term f is involved with the first order derivative explicitly. An example is given to illustrate the main result.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.
