In this article, we construct sufficient conditions that secure the non-emptiness and
compactness of the set of antiperiodic solutions of an impulsive fractional differential …

systems with dependence on the first d Page 1 Chapter 1 Third-order three point systems with …

In this work, we introduce a new definition for the fractional differential operator that
generalizes several well-known fractional differential operators. In fact, we introduce the …

In this paper, we improved recent results on the existence of solutions for nonlinear
fractional boundary value problems containing the Atangana-Baleanu fractional derivative of …

In this paper, we introduce the concept of the weighted generalized Atangana-Baleanu
fractional derivative. We prove the existence of the stability of solutions of non-local …

The time-scale tolerance for linear ordinary impulsive differential equations is introduced.
How large the time-scale tolerance is directly reflects the degree to which the qualitative …

A new measure of robust stability for linear ordinary impulsive differential equations with
periodic structure is introduced, based on the impulse extension concept. This new stability …
