POSITIVE SOLUTIONS FOR BOUNDARY VALUE PROBLEMS INVOLVING NONLINEAR FRACTIONAL q–DIFFERENCE EQUATIONS
نویسنده
چکیده
In this work, we investigate the eigenvalue intervals of nonlinear boundary value problems involving fractional q -difference equations by means of the properties of the Green function and Guo-Krasnosel’skii fixed point theorem on cones. Furthermore, some sufficient conditions for the nonexistence and existence of at least one or two positive solutions for the boundary value problem are established. As applications, some examples are presented to illustrate the main results. Mathematics subject classification (2010): 34K20, 92B20.

متن کاملPositive Solutions for Nonlinear Caputo Type Fractional q-Difference Equations with Integral Boundary Conditions
Since Al-Salam [1] and Agarwal [2] introduced the fractional q-difference calculus, the theory of fractional q-difference calculus itself and nonlinear fractional q-difference equation boundary value problems have been extensively investigated by many researchers. For some recent developments on fractional q-difference calculus and boundary value problems of fractional q-difference equations, s...

متن کاملA distinct numerical approach for the solution of some kind of initial value problem involving nonlinear q-fractional differential equations
The fractional calculus deals with the generalization of integration and differentiation of integer order to those ones of any order. The q-fractional differential equation usually describe the physical process imposed on the time scale set Tq. In this paper, we first propose a difference formula for discretizing the fractional q-derivative of Caputo type with order and scale index . We es...
