DESCRIPTION:Speaker:  Jesse Huang (University of Alberta)\n\nTitle: Geometr
 ic construction of toric NCRs\n\nAbstract: The Rouquier dimension of a tor
 ic variety is recently shown to be achieved by the Frobenius pushforward o
 f O via coherent-constructible correspondence. From the perspective of non
 commutative geometry\, this result leads to a geometric construction of to
 ric NCR of the invariant ring of the Cox ring with respect to a multi-grad
 ing which also gives the information about its global dimension. From the 
 perspective of mirror symmetry\, the same construction provides a universa
 l ``wall skeleton'' capturing VGIT wall-crossings\, which contains a windo
 w for each chamber as a full subcategory. From the perspective of commutat
 ive algebra\, the same construction indicates the existence of virtual res
 olutions of the multigraded diagonal bimodule\, which agrees with a recent
  result of Hanlon-Hicks-Larzarev constructing one such resolution explicit
 ly. In this talk\, I will survey these perspectives. The talk is based on 
 joint works with P. Zhou\, joint works with D. Favero\, and work in progre
 ss with D. Favero.
