Existence theory for $\psi$-Caputo fractional differential equations

UDC 517.9 The target of this paper is to handle a nonlocal boundary-value problem for a specific kind of nonlinear fractional differential equations encapsuling a collective fractional derivative known as the $\psi$-Caputo fractional operator. The applied fractional operator generated b...

description UDC 517.9 The target of this paper is to handle a nonlocal boundary-value problem for a specific kind of nonlinear fractional differential equations encapsuling a collective fractional derivative known as the $\psi$-Caputo fractional operator. The applied fractional operator generated by the kernel is of the following kind: $k(t,s)=\psi (t)-\psi(s).$  The existence of the solutions of the above-mentioned equations is tackled by using Mönch's fixed-point theorem combined with the technique of measures of noncompactness. In addition, we discuss the problem of stability within the scope of the Ulam–Hyers stability criteria for the main fractional system.  Finally, an example is given to illustrate the viability of the reported results.

УДК 517.9 Теорія існування для дробово-раціональних $\psi$-Капуто рівнянь Метою цієї роботи є розв'язання нелокальної крайової задачі для певного типу нелінійних диференціальних рівнянь з частинними похідними, що містять колективну дробову похідну, відому як дробовий оператор $\psi$-Капуто. Дробовий оператор, що використовується, згенеровано ядром. Він має вигляд $k(t,s)=\psi (t)-\psi(s).$  Існування розв'язків вищезгаданих рівнянь досліджується за допомогою теореми Монча про фіксовану точку в поєднанні з технікою мір некомпактності. Крім того, обговорено проблему стійкості для основної системи дробових рівнянь в рамках критеріїв стійкості Улама–Хаєрса.  Насамкінець наведено приклад, який ілюструє життєздатність отриманих результатів.
