摘要

We study the bilinear functor \(\mathfrak B\) B that associates to a Banach space X the Banach space \(\mathfrak B(X)\) B ( X ) of scalar bilinear bounded forms on X. We obtain its injective and projective derivatives, compute its projective and injective stabilization and introduce and compute its coprojective and coinjective stabilizations.
