DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HKUST-AG/7/"
 >Quasimaps to quivers with potentials</a>\nby Gufang Zhao (University of M
 elbourne) as part of Algebra and Geometry Seminar @ HKUST\n\nLecture held 
 in CYTG001.\n\nAbstract\nThis talk concerns non-compact GIT quotient of a 
 vector space\, in the presence of an abelian group action and an equivaria
 nt regular function (potential) on the quotient. We define virtual counts 
 of quasimaps from prestable curves to the critical locus of the potential.
  The construction borrows ideas from the theory of gauged linear sigma mod
 els as well as recent development in shifted symplectic geometry and Donal
 dson-Thomas theory of Calabi-Yau 4-folds. Examples of virtual counts arisi
 ng from quivers with potentials are discussed. This is based on work in pr
 eparation\, in collaboration with Yalong Cao.\n
