In this study, Chebyshev polynomials have been applied to construct an approximation method attain the solutions of linear fractional Fredholm integro-differential equations (IDEs). By method, IDE has transformed into a algebraic system with aid collocation points. conformable derivatives calculated in terms polynomials. Using results these calculations, matrix relation for was attained first t...

This paper focuses on the approximate controllability of Hilfer fractional neutral Volterra integro-differential inclusions via almost sectorial operators. Almost operators, differential, Leray-Schauder fixed point theorem and multivalued maps are used to prove result. We start by emphasizing existence a mild solution demonstrate system. In addition, an example is presented principle.
