Abstract
We introduce and study a generalization of the notion of exact operator space that we call subexponential Using Random Matrices we show that the factorization results of Grothendieck type that are known in the exact case all extend to the subexponential case but we exhibit a continuum of distinct examples of nonexact subexponential operator spaces as well as a Calgebra that is subexponential with constant 1 but not exact We also show that OH R + C and maxℓ2 or any other maximal operator space are not subexponential
