In this paper, a class of impulsive functional differential systems is investigated. It is proved that for the asymptotic stability of the zero solution of the system considered, it is sufficient that only some components of the right-hand side of the system are bounded for unbounded values of time. For functional differential equations without impulses, similar results were proved by Burton an...

In this paper, robust finite-time consensus of a group nonlinear multi-agent systems in the presence communication time delays is considered. particular, appropriate delay-dependent strategies which are less conservative suggested. Sufficient conditions for deterministic and stochastic disturbances presented. The don’t need to be invariant, uniform, symmetric, or even known. only required condi...

In this article, a resilient consensus analysis of fractional-order nonlinear leader and follower systems with input distributed delays is assumed. To make controller design more practical, it considered that the not implemented as is, disturbance term incorporated into part. A multi-agent system’s topology ahead to weighted graph which may be directed or undirected used. The article examines s...

‎we prove the existence of ppf dependent coincidence points for a pair of single-valued and multi-valued mappings satisfying generalized contractive conditions in banach spaces‎. ‎furthermore, the ppf dependent fixed point and ppf dependent common fixed point theorems for multi-valued mappings are proved.

The purpose of this literature review was to identify and describe recent empirical studies of childbirth education outcomes and to identify areas for further study. The search produced 63 studies; only 12 met the inclusion criteria. The literature demonstrated inconclusive evidence regarding the effectiveness of childbirth education. None of the studies used a theoretical framework that propos...

In this work, stability analysis for a class of switched nonlinear time-delay systems is performed by applying Lyapunov–Krasovskii and Lyapunov–Razumikhin approaches. It assumed that each subsystem in the family homogeneous (of positive or negative degree) asymptotically stable delay-free setting. The cases existence common multiple functionals function are explored. scenarios with synchronous ...
