 ">Wall-crossing phenomenon for Newton-Okounkov bodies</a>\nby Laura Escoba
 r (Washington) as part of Online Nottingham algebraic geometry seminar\n\n
 \nAbstract\nA Newton-Okounkov body is a convex set associated to a project
 ive variety\, equipped with a valuation. These bodies generalize the theor
 y of Newton polytopes and the correspondence between polytopes and project
 ive toric varieties. Work of Kaveh-Manon gives an explicit link between tr
 opical geometry and Newton-Okounkov bodies. We use this link to describe a
  wall-crossing phenomenon for Newton-Okounkov bodies. As an example\, we d
 escribe wall-crossing formula in the case of the Grassmannian Gr(2\,m). Th
 is is joint work with Megumi Harada.\n
