Abstract Impulsive Volterra Integro-Differential Inclusions

open access: yesFractal and Fractional, 2023
In this work, we provide several applications of (a, k)-regularized C-resolvent families to the abstract impulsive Volterra integro-differential inclusions.

Impulsive Fractional Semilinear Integrodifferential Equations with Nonlocal Conditions

open access: yesJournal of Function Spaces, 2021
This paper is devoted to a class of impulsive fractional semilinear integrodifferential equations with nonlocal initial conditions. Based on the semigroup theory and some fixed point theorems, the existence theory of PC-mild solutions is established ...

A New Identity for Resolvents of Operators [PDF]

open access: yesInternational Journal of Analysis, 2013
A new identity for resolvents of operators is suggested. We show that in appropriate situations it is more convenient than the Hilbert identity. In particular, we establish a new invertibility condition for perturbed operators as well as new bounds for the spectrum of perturbed operators.

RESOLVENT ESTIMATES OF THE DIRAC OPERATOR

open access: yesAnalysis, 1995
We shall investigate the asymptotic behavior of the extended resolvent R(s) of the Dirac operator as |s| increases to infinity, where s is a real parameter. It will be shown that the norm of R(s), as a bounded operator between two weighted Hilbert spaces of square integrable functions on the 3-dimensional Euclidean space, stays bounded.

Nonlocal Problems for Fractional Differential Equations via Resolvent Operators

open access: yesInternational Journal of Differential Equations, 2013
We discuss the continuity of analytic resolvent in the uniform operator topology and then obtain the compactness of Cauchy operator by means of the analytic resolvent method.
