Given a vector space V of homogeneous polynomials of the same degree over an infinite field, consider a generic subspace W of V. The main result of this paper is a lower-bound (in general sharp) for ...

A $\sigma$-weakly closed subspace $\mathscr{S}$ of $B(\mathscr{H})$ is said to have Property $S_\sigma$ if for any $\sigma$-weakly closed subspace $\mathscr{J}$ of a ...
