Classical polynomial inequalities for quadratic forms on an octagonal sector

Manwook Han, Sun Kwang Kim, Juan B. Seoane--Sepúlveda

We establish a collection of sharp inequalities for real quadratic forms on the first-quadrant sector of a regular octagon. Starting from the complete extreme-point description of…

New Results in Analysis of Orlicz-Lorentz spaces

Luis Bernal-González, Daniel L. Rodríguez-Vidanes, Juan B. Seoane-Sepúlveda +1

In this article, we investigate the existence of closed vector subspaces (i.e.spaceability) in various nonlinear subsets of Orlicz-Lorentz spaces , equipped with the Lux…
