Toric degenerations of cluster varieties II
Algebra and Geometry Seminar
19th February 2019, 1:00 pm – 2:00 pm
Howard House, 4th Floor Seminar Room
In this talk I will give an example of the general theory introduced by Tim in the previous talk and focus on the Grassmannian. Rietsch and Williams introduced toric degenerations of Grassmannian relying on plabic graphs- combinatorial objects that encode part of the Grassmannians cluster structure. Our theory can be used to understand their degeneration and further show that it agrees with the Aprin-degeneration of Gross-Hacking-Keel-Kontsevich.
