On the Geometry of the Birkhoff Polytope. II. The Schatten $p$ -norms

Ludovick Bouthat, Javad Mashreghi, Frédéric Morneau-Guérin

In the first of this series of two articles, we studied some geometrical aspects of the Birkhoff polytope, the compact convex set of all $n \times n$ doubly stochastic matrices, na…

On the Geometry of the Birkhoff Polytope. I. The operator $ℓ_{n}^{p}$ -norms

Ludovick Bouthat, Javad Mashreghi, Frédéric Morneau-Guérin

The geometry of the Birkhoff polytope, i.e., the compact convex set of all $n \times n$ doubly stochastic matrices, has been an active subject of research. While its faces, edges a…

On a question of Erdős on doubly stochastic matrices

Ludovick Bouthat, Javad Mashreghi, Frédéric Morneau-Guérin

In a celebrated paper of Marcus and Ree (1959), it was shown that if $A = [a_{ij}]$ is an $n \times n$ doubly stochastic matrix, then there is a permutation $σ \in S_{n}$ such that $\su…
