15 p, 382.9 KB Sharp Gagliardo-Nirenberg inequalities via symmetrization / Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Milman, Mario (Florida Atlantic University. Department of Mathematics)
We prove Gagliardo-Nirenberg inequalities using certain new symmetrization inequalities. Our methods are elementary and can be applied in a very general context.

20 p, 355.6 KB Galois descent for the gonality of curves / Roé Vellvé, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Xarles Ribas, Francesc Xavier (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We determine conditions for the invariance of the gonality under base extension, depending on the numeric invariants of the curve. More generally, we study the Galois descent of morphisms of curves to Brauer-Severi varieties, and also of rational normal scrolls.
