Développement en série de fonctions holomorphes des fonctions d'une classe de Gevrey sur l'intervalle [-1;1]

Abstract: We characterize Gevrey functions on the unit interval [−1, 1] as sums of holomorphic functions in specific neighborhoods of [−1, 1]. As an application of our main theorem, we perform a simple proof for Dyn'kin's theorem of pseudoanalytic extension for Gevrey classes on [−1, 1].

“…Our purpose in this paper is to prove, under some regularity conditions on the data, the solvability in a Gevrey class of the form G k,− 1 ([− 1, 1]) of a class of nonlinear FFDE. Our approach is mainly based on a theorem that we have proved in [41]. e notion of fractional calculus we are interested in is the Caputo fractional calculus.…”

“…[10]), that u |[d,1] belongs to the Gevrey class G k ([d, 1]). But since d is an arbitrary element of ]−1, 1[ and u is of class C 1 on [−1, 1] , it follows that u belongs to the Gevrey class G k,−1 ([−1, 1]).…”

“…Improving the methods of Ecalle and Belghiti, we obtained in [5] a characterization of the functions of a Gevrey class on [−1, 1] as sums of series of holomorphic functions in suitable neighborhoods of [−1, 1], and here we generalize this method to some Carleman classes on [−1, 1]. As an application of our main theorem, we derive an alternative construction of Dyn'kin's pseudoanalytic extension for these Carleman classes.…”
