Spaces with the maximal projection constant revisited

Tomasz Kobos

Let $n \geq 2$ be an integer such that an equiangular set of vectors $w_{1}, \dots, w_{d}$ of the maximal possible cardinality (that is, attaining the classical Gerzon upper bound) ex…

$2$ -strong uniqueness of a best approximation and of minimal projections in complex polytope norms and their duals

Tomasz Kobos, Grzegorz Lewicki

We study a property of $2$ -strong uniqueness of a best approximation in a class of finite-dimensional complex normed spaces, for which the unit ball is an absolutely convex hull of…
