Periodic solutions of abstract neutral functional differential equations
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2013-08-02)
We characterize the existence of periodic solutions of some abstract neutral functional differential equations with finite and infinite delay when the underlying space is a UMD space. (C) 2011 Elsevier Inc. All rights reserved.
Asymptotically almost periodic solutions for abstract neutral integro-differential equations
(ELSEVIER SCIENCE INC, 2011)
We study the existence of asymptotically almost periodic classical solutions for a class of abstract neutral integro-differential equation with unbounded delay. A concrete application to partial neutral integro-differential ...
Remarks on the existence and uniqueness of periodic solution for nth-order functional differential equations with infinite delay
(2018-01-01)
In this work we apply the coincidence degree theory to establish a result on the existence and uniqueness of periodic solution for a class of nth-order functional differential equations with infinite delay. An example is ...
On the Periodic Solutions of the Five-Dimensional Lorenz Equation Modeling Coupled Rosby Waves and Gravity Waves
(2017-06-15)
Lorenz studied the coupled Rosby waves and gravity waves using the differential system U = -VW + bVZ, V = UW - bUZ, W = -UV, Ẋ = -Z, Ż = bUV + X. This system has the two first integrals H1 = U2 + V2, H2 = V2 + W2 + X2 + ...
On Anti-Periodic Solutions for a Class of Impulsive Retarded Functional Differential Equations
(2017-08-01)
In this paper, some new results on the existence and uniqueness of anti-periodic solution for a first-order impulsive functional differential equation with delay are obtained. The main tool to be employed here is the ...
Multiple solutions for periodic perturbations of a delayed autonomous system near an equilibrium
(American Institute of Mathematical Sciences, 2019)
Small non-autonomous perturbations around an equilibrium of a nonlinear delayed system are studied. Under appropriate assumptions, it is shown that the number of T-periodic solutions lying inside a bounded domain Ω ⊂ R N ...
