DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HubEG/2/">Qu
 asimaps and stable pairs</a>\nby Henry Liu (Oxford) as part of Events Hub:
  Enumerative geometry\n\n\nAbstract\nQuasimaps to Hilbert schemes of surfa
 ces S resemble the Donaldson-Thomas theory of S times a curve. This corres
 pondence can be made precise for the appropriate DT stability chamber\, na
 mely the so-called Bryan-Steinberg stable pairs. I will explain why BS pai
 rs and quasimaps are equivalent whenever they are comparable. Quasimaps ha
 ve been used recently to study 3d mirror symmetry\, which when pushed thro
 ugh this equivalence has implications for some aspects of sheaf-counting t
 heories\, including the (DT) crepant resolution conjecture.\n\nZoom: 849 9
