Absolutely Summing Operators on non commutative $C^{\ast }$-algebras and applications

Narcisse Randrianantoanina

Let $E$ be a Banach space that does not contain any copy of ${\ell }^1$ and $\A$ be a non commutative $C^{\ast }$-algebra. We prove that every absolutely summing operator from $\A$ into $E^…
