Oscillation of Hilfer-Prabhakar fractional differential equations with multiple sublinear neutral terms

This paper investigates a class of Hilfer-Prabhakar fractional differential equations involving multiple sublinear neutral terms. It addresses the analytical difficulties caused by the presence of multiple sublinear neutral terms and establishes a series of oscillation criteria for this class of equations. The obtained results further enrich and refine the existing theoretical framework for Caputo-type and Hilfer-type fractional differential equations. Finally, numerical simulation examples are provided to verify the correctness of the theoretical results.
