Abstract
Dans ce travail, on montre que (M(T),c0(Z))θ=(L1,c0(Z))θ, 0<θ<1. Dans la suite on montre pour le couple d'interpolation (C0,C1) trouv\'e par Garling-Smith qu'il existe un isomorphisme Uθ:(C0,C0+C1)θ,p→(C1,C0+C1)θ,p (resp. Uθ:(C0,C0+C1)θ→(C1,C0+C1)θ) tel que sa restriction \`a Cθ,p (resp. \`a Cθ) est un isomorphisme : Cθ,p→C1−θ,p (resp. Cθ→C1−θ). -- In this work we show that (M(T),c0(Z))θ=(L1,c0(Z))θ, 0<θ<1. In the following we show for the interpolation couple found by Garling-Smith that there exists an isomorphism Uθ:(C0,C0+C1)θ,p→(C1,C0+C1)θ,p (resp. Uθ:(C0,C0+C1)θ→(C1,C0+C1)θ) such that its restriction to Cθ,p (resp. to Cθ) is an isomorphism : Cθ,p→C1−θ,p (resp. Cθ→C1−θ).
