 Title: Caractérisation Des Espaces 1-Matriciellement Normés Authors: Le Merdy, ChristianMezrag, Lahcéne Keywords: Espace d’opérateursEspace P-Matriciellement NorméOpérateur Complétement Borné Issue Date: 2002 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 28, No 3, (2002), 201p-206p Abstract: Let X be a closed subspace of B(H) for some Hilbert space H. In [9], Pisier introduced Sp [X] (1 ≤ p ≤ +∞) by setting Sp [X] = (S∞ [X] , S1 [X])θ , (where θ =1/p , S∞ [X] = S∞ ⊗min X and S1 [X] = S1 ⊗∧ X) and showed that there are p−matricially normed spaces. In this paper we prove that conversely, if X is a p−matricially normed space with p = 1, then there is an operator structure on X, such that M1,n (X) = S1 [X] where Sn,1 [X] is the finite dimentional version of S1 [X]. For p = 1, we have no answer. URI: http://hdl.handle.net/10525/498 ISSN: 1310-6600 Appears in Collections: Volume 28 Number 3
