Abstract:
In order to simplify the resolution of Fredholm and Volterra's second type integral equations, we propose a new approach based on the Adomian Decompositional Method (ADM). We test the new approach on several examples with success.

Abstract:
The work addressed in this article consists in constructing the exact solutions, where they exist, of fractional Fredholm-type integro-differential equations in the sense of Caputo. Our results are obtained using the SBA method. The simplification of the approach, the analysis of its convergence, and the generalization of this method to these types of highly nonlinear equations constitute our scientific contribution.

Abstract:
This paper discusses the existence and uniqueness of pseudo almost periodic solutions to a class of partial neutral functional-differential equations. Under some suitable assumptions, existence and uniqueness results are obtained. An example is given to illustrate abstract results.

Abstract:
In this paper , we study the existence of a weak solutions for the
initial-boundary value problems of the strongly nonlinear degenerated parabolic
equation,
where
A is a Leray-lions operator acted from
Lp(0,T,W01,p(Ώ,w)) into its dual. g(x,t,u,∇ u)
is a nonlinear term with critical growth condition with respect to ∇ u
and no growth with respect to u.
The source term f is assumed to belong to Lp'(0,T,W-1,p'(Ώ,w*)).
∂u
+A(u)+g(x,t,u,∇ u)=f

Abstract:
By working out an appropriate technique of relations and relators and extending the ideas of the direct methods of Z. Gajda and R. Ger, we prove some generalizations of the stability theorems of D. H. Hyers, T. Aoki, Th. M. Rassias and P. Găvruţă in terms of the existence and unicity of 2-homogeneous and additive approximate selections of generalized subadditive relations of semigroups to vector relator spaces. Thus, we obtain generalizations not only of the selection theorems of Z. Gajda and R. Ger, but also those of the present author.
