Fractional neutral integro-differential dynamical systems with periodic Boundary Value Problems

The primary objective of this study is to comprehensively investigate the outcomes concerning the existence and Ulam stability of a fractional dynamic system, specically one involving a neutral partial integro-differential equation with periodic boundary conditions on time scales, using the Caputo fractional nabla derivative.

The study applies standard fixed point methods(Krasnoselskii fixed point theorem) to derive its results, with a focus on controllability and Ulam stability. Additionally, the practical relevance of the theoretical findings is showcased through an illustrative example, which includes a graphical representation through MATLAB Software.

Future work will focus on advancing numerical methods for fractional systems with delays
or nonlocal conditions, exploring new control strategies, and applying these systems
to communication networks and biomedical elds. Key areas include enhancing stability
analysis and leveraging machine learning for optimized control.
