Periodic boundary value problem for second order integro-ordinary differential equations with general kernel and Carathéodory nonlinearities.
Periodic solutions for nonlinear Volterra integrodifferential equations in Banach spaces
In this paper we examine periodic integrodifferential equations in Banach spaces. When the cone is regular, we prove two existence theorems for the extremal solutions in the order interval determined by an upper and a lower solution. Both theorems use only the order structure of the problem and no compactness condition is assumed. In the last section we ask the cone to be only normal but we impose a compactness condition using the ball measure of noncompactness. We obtain the extremal solutions...
Periodic solutions for second order integro-differential equations with infinite delay in Banach spaces
We study the maximal regularity on different function spaces of the second order integro-differential equations with infinite delay (0 ≤ t ≤ 2π) with periodic boundary conditions u(0) = u(2π), u’(0) = u’(2π), where A is a closed operator in a Banach space X, α ∈ ℂ, and a,b ∈ L¹(ℝ₊). We use Fourier multipliers to characterize maximal regularity for (P). Using known results on Fourier multipliers, we find suitable conditions on the kernels a and b under which necessary and sufficient conditions...

Problème de Cauchy pour le système intégro-différentiel d'Einstein-Liouville
Démonstration d’un théorème d’existence de la solution du problème de Cauchy pour les équations intégro-différentielles de la dynamique d’un gaz relativiste soumis à son propre champ de gravitation : les inégalités énergétiques des sytèmes hyperboliques et un théorème de point fixe sont utilisés. Les résultats sont obtenus dans des espaces de Sobolev pour le champ de gravitation et pour le produit par de la fonction de distribution (, vecteur temporel).
