L’étude du présent article s’inspire du résultat de Gangl, Kaneko et Zagier sur connexion entre les valeurs zêta doubles et les formes modulaires. Nous introduisons la série d’Eisenstein double E r,s en caractéristique positive avec les valeurs zêta doubles ζ A (r,s) comme terme constant et calculons les t-expansions de la série d’Eisenstein double. De plus, on en déduit les relations de shuffle de deux séries d’Eisenstein qui correspondent aux relations de shuffle des valeurs zêta doubles dans [4].

The study of the present paper is inspired by Gangl, Kaneko and Zagier’s result of the connection with double zeta values and modular forms. We introduce double Eisenstein series E r,s in positive characteristic with double zeta values ζ A (r,s) as their constant term and compute the t-expansions of the double Eisenstein series. Moreover, we derive the shuffle relations of double Eisenstein series which match the shuffle relations of double zeta values in [4].
