A simple proof of the Grunbaum conjecture

Beata Deregowska, Barbara Lewandowska

Let $λ_{K} (m)$ denote the maximal absolute projection constant over the subspaces of dimension $m$ . Apart from the trivial case for $m = 1$ , the only known value of $λ_\mathb…

On the value of the fifth maximal projection constant

Beata Derȩgowska, Matthew Fickus, Simon Foucart +1

Let $λ (m)$ denote the maximal absolute projection constant over real $m$ -dimensional subspaces. This quantity is extremely hard to determine exactly, as testified by the fact that…
