Solutions of fractional nabla difference equations - existence and uniqueness

Jagan Mohan Jonnalagadda

Abstract. In this article, we discuss existence, uniqueness and dependency of solutions of nonlinear fractional nabla difference equations in a Banach space equipped with a suitable norm, using the contractive mapping approach. As an application of the established results we present and analyse a few examples.

Keywords: nabla difference, exponential function, fixed point, existence, uniqueness, continuous dependence.

Mathematics Subject Classification: 34A08, 39A10, 39A99.
