Metric geometry of infinite dimensional Lie groups and their homogeneous spaces
(De Gruyter, 2019-09)
We study the geometry of Lie groups G with a continuous Finsler metric, in presence of a subgroup K such that the metric is right-invariant for the action of K. We present a systematic study of the metric and geodesic ...

Quotient p-Schatten metrics on spheres
(Unión Matemática Argentina, 2017-04)
Let S(H) be the unit sphere of a Hilbert space H and Up(H) thegroup of unitary operators in H such that u−1 belongs to the p-Schatten idealBp(H). This group acts smoothly and transitively in S(H) and endows it witha natural ...
Column symmetric polynomials
(Amiens, 2019-09)
Nous étudions l’algébre des polynômes en une m x n matrice de variables sur un anneau contenant les rationnels, sujette à la condition que le produit de deux variables appartenant à une même colonne est nul. Nous montrons ...
