CAUCHY PROBLEM FOR THE EQUATIONS WITH FRACTIONAL OF RIEMANN-LIOUVILLE DERIVATIVES

摘要

In this article, we study the question of the solvability of an analogue of the Cauchy problem for ordinary differential equations with fractional Riemann-Liouville derivatives on the unbounded right-hand side in certain function spaces. The solvability conditions of the problem under consideration in given function spaces, as well as the existence conditions of a unique solution are presented. The study uses the method of reducing the problem to the second-kind Volterra equation, the Schauder principle of a fixed point in a Banach space, and the Banach-Cachoppoli principle of a fixed point in a complete metric space.
