Norm of infinite doubly stochastic matrices
Ludovick Bouthat, Javad Mashreghi, Raphaël Vo
In finite dimensions, every doubly stochastic matrix has the -operator norm equal to for all . However, in the infinite-dimensional setting, this pr…

On the convergence of doubly stochastic Markov chains
Ludovick Bouthat, Nicolas Doyon, Javad Mashreghi +1
We characterize the asymptotic behavior of time-homogeneous doubly stochastic Markov chains. Our investigation revolves around understanding the dynamics of products of doubly stoc…

Weighted Hardy Inequalities for Nested Averages
Ludovick Bouthat, Pierre-Olivier Parisé
We study a family of Hardy-type inequalities for weighted averages over nested subsets of a measure space. Given a partition of a measure space and a weight function , we consid…
