Extreme points for positive forms on \(\ell ^ p\)
The author characterises in the finite dimensional case the extreme points of the convex sets of the bilinear forms on \(\ell^ p\times \ell^ q\) \((p>1\), \(q>1\), \(p^{-1}+q^{-1}\leq 1)\) which have non- negative coefficients, norm bounded by one. The results are then extended to the multilinear case.
