Le 04 février 2020 à 10h30 en A108, Gérard Duchamp nous parlera de : Domains and a (new ?) family of entire functions II

Résumé : After having recalled and proved the set of "marvelous identities" evoked last week through an Umbral coding of "the plane", we construct, after Minh's work, a regularized character of the stuffle algebra which transports, point-by-point the Hausdorff group of the stuffle algebra. We provide as well the $q$-analogue and set some open questions.
