DESCRIPTION:We establish connections between two objects\, naturally arisi
ng in the theory of the Kadomtsev-Petviashvily equation: totally positive
Grassmannians and rational degenerations of the M-curves (Riemann surfaces
with an anitiholomorphic involutuin and the maximal possible number of re
al ovals) with a collection of marked points. More precisely\, we show tha
t\, at least all points from the principal cell of the Grassmannian can be
obtained from degenerate M-curves. (Joint work with Simonetta Abenda (Uni
versita degli Studi di Bologna).)\n\nhttps://indico.math.cnrs.fr/event/926
