Abstract:A fixed point theorem for condensing maps due to Martelli combined with theories of a strongly continuous cosine family of bounded linear operators is used to investigate the existence of solutions to second order impulsive neutral functional integrodifferential inclusions with infinite delay in Banach spaces.Keywords: Second order impulsive integrodifferential inclusion, cosine functions of operators, mild solution, Martelli's fixed point theorem.
“…Further investigation started with a discussion of previously published works [10,[27][28][29]. Specifically, the existence and uniqueness of the mild solutions and approximate controllability of fractional evolution equations with deformable derivatives were investigated in [29,30]…”
This article deals with the existence and uniqueness of solutions, as well as the approximate controllability of fractional neutral differential equations (ACFNDEs) with deformable derivatives. The findings are achieved using Banach’s, Krasnoselskii’s, and Schauder’s fixed-point theorems and semigroup theory. Three numerical examples are used to illustrate the application of the theories discussed in the conclusion.

“…For this reason, last years several researchers have studied various aspects of the theory. We mention here [1,2,6,8,12,13,20,21,24,26,29] and references in these works for the motivations of the theory.…”
In this work we are concerned with the existence of fixed points for multivalued maps defined on Banach spaces. Using the Banach spaces scale concept, we establish the existence of a fixed point of a multivalued map in a vector subspace where the map is only locally Lipschitz continuous. We apply our results to the existence of mild solutions and asymptotically almost periodic solutions of an abstract Cauchy problem governed by a first-order differential inclusion. Our results are obtained by using fixed point theory for the measure of noncompactness.
“…For this reason this topic has attracted the attention of many authors in the last time. We only mention here the papers [7][8][9][10][11][12][13][14][15][16][17] which are directly related with the objective of this paper.…”

“…On the other hand, it is well known that retarded functional differential equations are used to model important concrete phenomena. For general aspects of the theory of partial differential equations with delay we refer to [27], and for functional differential inclusions we refer to [7,9,[12][13][14]28]. In similar way, there exists an extensive literature concerning abstract second order problems.…”
In this work we establish some existence results for abstract second order Cauchy problems modeled by a retarded differential inclusion involving nonlocal and impulsive conditions. Our results are obtained by using fixed point theory for the measure of noncompactness.
