Periodic solutions of abstract neutral functional differential equations with infinite delay

Abstract

We establish the existence of mild solutions and periodic mild solutions for a class of abstract rst-order non-autonomous neutral functional differential equations with innite delay in a Banach space.

Almost Periodic Solution to a Non-Instantaneous Impulsive Differential Equation With Deviating Arguments Tanmoy Barman, Duranta Chutia and Rajib Haloi

“…where A is infinitesimal generator of a strongly continuous semigroup. Herniquez and Vasquez [13] proved the existence of almost periodic solution to (2.5). These types of equations are often referred to as the abstract retarded functional differential equation.…”

A discussion on boundary controllability of nonlocal impulsive neutral integrodifferential evolution equations

“…Akdad et al 35 presented existence results for the Stepanov 𝜇-pseudo almost automorphic and periodic mild solution. Zhou and Jiao, Vijayakumar and Udhayakumar, Hernández and O'Regan, and Henriquez [36][37][38][39] investigated existence and uniqueness for certain classes of the fractional system by employing the fixed point approach, fractional theories, and measure of noncompactness, etc.…”

Approximate controllability of a semi-linear neutral evolution system with infinite delay

“…See [9,10] for a more practical background of this kind of equations. In the past years, existence results and asymptotic properties of solutions for this type of neutral systems have been investigated by many authors (e.g., [11][12][13][14][15][16][17]).…”
