A Finite-order Characterization of Entrywise Positivity Preservers

Ludovick Bouthat, Dominique Guillot

Fix $I = (0, ρ)$ , where $0 < ρ \leq \infty$ , and let $P_{n} (I)$ be the set of positive semidefinite $n \times n$ matrices with entries in $I$ . A longstanding problem in matrix the…

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 $m$ , we consid…
