DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IBSCGP/9/">S
 cattering diagrams from blowups of toric surfaces</a>\nby Hansol Hong (Yon
 sei) as part of IBS-CGP weekly zoom seminar\n\n\nAbstract\nGross-Hacking-K
 eel has shown that any cluster variety can be obtained by a sequence of (n
 ontoric) blow-ups and blow-downs starting from a toric variety. Motivated 
 by this\, we study the effect of blowup on the Lagrangian torus fibration 
 on a toric surface. In particular\, we will see that if the blowup points 
 lie over the codimension one strata of the toric variety\, the resulting f
 ibration on the blowup produces a scattering diagram that matches with the
  one constructed by Gross-Pandharipande-Siebert using algebraic curve coun
 ting. The talk is based on the work in progress jointly with Sam Bardwell-
 Evans\, Man-Wai Mandy Cheung and Yu-Shen Lin.\n
