Nonlocal conditions for differential inclusions in the space of functions of bounded variations

open access: yesAdvances in Difference Equations, 2011
We discuss the existence of solutions of an abstract differential inclusion, with a right-hand side of bounded variation and subject to a nonlocal initial condition of integral type.

Existence theory for implicit fractional q-difference equations in Banach spaces

open access: yes, 2022
This paper deals with some existence results for a class of implicit fractional q-difference equations. The results are based on the fixed point theory in Banach spaces and the concept of measure of noncompactness. An illustrative example is given in the

Method of semidiscretization in time for quasilinearintegrodifferential equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 9, Page 469-478, 2004., 2004
We consider a class of quasilinear integrodifferential equations in a reflexive Banach space. We apply the method of semidiscretization in time to establish the existence, uniqueness, and continuous dependence on the initial data of strong solutions.

Method of semidiscretization in time to nonlinear retarded differential equations with nonlocal history conditions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 37, Page 1943-1956, 2004., 2004
This paper deals with the applications of the method of semidiscretization in time to a nonlinear retarded differential equation with a nonlocal history condition. We establish the existence and uniqueness of a strong solution. Finally, we consider some applications of the abstract results.

Existence, uniqueness, and regularity of solutions to semilinear retarded differential equations

open access: yesInternational Journal of Stochastic Analysis, Volume 2004, Issue 3, Page 213-219, 2004., 2004
In the present work, we consider a semilinear retarded differential equation in a Banach space. We first establish the existence and uniqueness of a mild solution and then prove its regularity under different additional conditions. Finally, we consider some applications of the abstract results.
