We study the bilinear functor \(\mathfrak B\) that associates to a Banach space X the Banach space \(\mathfrak B(X)\) 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.
