DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGARTOS/28/
 ">Wall-crossing phenomenon for Newton--Okounkov bodies</a>\nby Laura Escob
 ar (Washington U. in St Louis) as part of (LAGARTOS) Latin American Real a
 nd Tropical Geometry Seminar\n\n\nAbstract\nA Newton-Okounkov body is a co
 nvex set associated to a projective variety\, equipped with a valuation. T
 hese bodies generalize the theory of Newton polytopes and the corresponden
 ce between polytopes and projective toric varieties. Work of Kaveh-Manon g
 ives an explicit link between tropical geometry and Newton-Okounkov bodies
 . We use this link to describe a wall-crossing phenomenon for Newton-Okoun
 kov bodies. As an example\, we describe wall-crossing formula in the case 
 of the Grassmannian Gr(2\,m). This is joint work with Megumi Harada.\n
