On exponential stability of functional differential equations with variable impulse perturbations
(Khayyam Publ Co Inc, 2014-07-01)
We consider a class of functional differential equations subject to perturbations, which vary in time, and we study the exponential stability of solutions of these equations using the theory of generalized ordinary ...
On retarded differential equations with impulses
We are concerned with the effect of impulses in retarded functional differential equations. By using fixed point techniques we prove the existence of periodic solutions of some impulsive equations. For a system of retarded ...
Weak Asymptotic Methods For Scalar Equations And Systems
(Academic Press Inc Elsevier ScienceSan Diego, 2016)
A new approach to linear interval differential equations as a first step toward solving fuzzy differential
This study uses a concept of interval differentiability, which was recently introduced, to formulate interval initial value problems involving linear interval differential equations. Differently from the approaches that ...
Poincare's problem in the class of almost periodic type functions
(Belgian Mathematical Soc Triomphe, 2015)
We consider the Poincare's classical problem of approximation for second order linear differential equations in the class of almost periodic type functions. We obtain an explicit form for solutions of these equations by ...
ANTIPERIODIC SOLUTIONS FOR nTH-ORDER FUNCTIONAL DIFFERENTIAL EQUATIONS WITH INFINITE DELAY
(Texas State Univ, 2016-02-02)
In this work, we establish the existence and uniqueness of antiperiodic solution for a class of nth-order functional differential equations with infinite delay. The main tool in our study is the coincidence degree theory. ...
EXISTENCE OF SOLUTIONS FOR A FRACTIONAL NEUTRAL INTEGRO-DIFFERENTIAL EQUATION WITH UNBOUNDED DELAY
(TEXAS STATE UNIVSAN MARCOS, 2012)
In this article, we study the existence of mild solutions for fractional neutral integro-differential equations with infinite delay.
Boundedness of solutions of retarded functional differential equations with variable impulses via generalized ordinary differential equations
(WILEY-V C H VERLAG GMBHWEINHEIM, 2012)
In this paper, we give sufficient conditions for the uniform boundedness and uniform ultimate boundedness of solutions of a class of retarded functional differential equations with impulse effects acting on variable times. ...
