The basic sequence problem for quasi-normed spaces
A quasi-normed complex vector space is called \(A\)-convex if it has an equivalent plurisubharmonic quasi-norm. It is proved that every \(A\)- convex quasi-normed space \(X\) contains basic sequences. Consequently, \(X\) has a proper closed infinite-dimensional subspace.
