Analysis of Hilfer Fractional Integro-Differential Equations with Almost Sectorial Operators

open access: yesFractal and Fractional, 2021
In this work, we investigate a class of nonlocal integro-differential equations involving Hilfer fractional derivatives and almost sectorial operators. We prove our results by applying Schauder’s fixed point technique.

On a Linear Differential Game of Pursuit with Integral Constraints in 2

open access: yesMathematics
In this paper, we study the stability, controllability, and differential game of pursuit for an infinite system of linear ODEs in ℓ2. The system we consider has a special right-hand side, which is not diagonal and serves as a toy model for controllable ...
