General fractional q-integrals and q-derivatives: a Sonin–Luchko q-kernel approach

摘要

This paper introduces a novel class of kernels for q-integral transforms, called symmetrical Sonin–Luchko q-kernels, with the goal of advancing the theory of general fractional q-calculus. Building upon the classical Sonin method and the recent results of Luchko on symmetrical Sonin kernels in the continuous setting, we develop a q-analogue using the q-Laplace integral transform. As a result, we derive new kernels that generalize the Riemann–Liouville q-integral and q-derivative kernels. In particular, we construct explicit Sonin q-kernels in terms of the q-Mittag–Leffler and q-Wright functions, thereby extending Luchko’s framework to the q-calculus setting.
