We study the existence of mild solutions for a new class of nonlocal fractional semilinear integrodifferential evolution equations with a nondensely defined closed linear operator involving the generalized \( \varphi \)-Caputo fractional derivative. By applying two fixed-point theorems for condensing operators, in combination with the \( C_0 \)-semigroup theory and the concept of noncompactness measure, we derive sufficient conditions for the existence of solutions. An illustrative example is presented to highlight the applicability and robustness of our theoretical findings. |

УДК 517.937, 517.98, 517.23 Результати щодо існування розв'язків дробових напівлінійних еволюційних рівнянь із $\varphi$-похідною Капуто Досліджено існування м'яких розв'язків для нового класу нелокальних дробових напівлінійних інтегро-диференці\-альних еволюційних рівнянь з усюди нещільно визначеним замкненим лінійним оператором, що містить узагальнену дробову похідну Капуто \(\varphi\)-типу. Із застосуванням двох теорем про нерухому точку для ущільнювальних операторів у поєднанні з теорією \(C_0\)-напівгруп і поняттям міри некомпактності отримано достатні умови існування розв'язків. Наведено ілюстративний приклад, який демонструє застосовність і стійкість отриманих теоретичних результатів.
