Fractional Differential Equations With Retardation and Anticipation

Abstract

In this chapter, we prove some existence and uniqueness results for a class of boundary and terminal value problems for implicit nonlinear k-generalized ψ -Hilfer fractional differential equations involving both retarded and advanced arguments. Further, examples are given to illustrate the viability of our results in each section. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
