In this paper, we consider integral boundary value problems of nonlinear fractional differential equations. Existence results of positive solutions for the problem are obtained based on the Guo-Krasnoselskii theorem and the Five functional fixed point theorem. Simple examples follow the main results in successive sections. [ABSTRACT FROM AUTHOR]

In this work, two different boundary value problems of fractional q-difference equation are discussed. The first one is fractional q-difference equation with integral boundary conditions and the other one is three point boundary value problem of fractional q-difference equation with p-Laplacian. By using fixed point theorems, some sufficient conditions that guarantee the existence and uniqueness of solutions are given. [ABSTRACT FROM AUTHOR]

In this paper, by using the Schauder fixed point theorem, we obtain the existence of positive solutions for discrete fractional boundary value problem. Also, we establish upper and lower solution for this problem. Our results extend some recent works in the literature. [ABSTRACT FROM AUTHOR]

In this study, existence of positive solutions are considered for second order boundary value problems on any time scales even in the case when y ≡ 0 may also be a solution. [ABSTRACT FROM AUTHOR]

This paper is concerned with the existence of multiple positive solutions for a functional dynamic equations with multi-point boundary conditions on time scales by using fixed point theorems in a cone. As an application, we also give an example to demonstrate our results. [ABSTRACT FROM AUTHOR]

In this paper, we are concerned with proving the existence of solutions for four point fractional differential equations with p-Laplacian operator. We obtain the existence of at least one solution for the problem applying Schauder fixed-point theorem. [ABSTRACT FROM AUTHOR]
