Approximate Solutions of an Extended Multi-Order Boundary Value Problem by Implementing Two Numerical Algorithms

In this paper, we establish several necessary conditions to confirm the uniqueness-existence of solutions an extended multi-order finite-term fractional differential equation with double-order integral boundary respect asymmetric operators by relying on Banach’s fixed-point criterion. We validate our study implementing two numerical schemes handle some Riemann–Liouville value problems and obtain approximate series that converge exact ones. particular, present examples illustrate closeness solutions.
