DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/44/">
 DT invariants of some 3CY quotients</a>\nby Sergey Mozgovoy (Trinity Colle
 ge Dublin\, Ireland) as part of Longitudinal Algebra and Geometry Open ONl
 ine Seminar (LAGOON)\n\n\nAbstract\nGiven a finite subgroup of SL3\, the c
 orresponding quotient singularity has a natural non-commutative crepant re
 solution\, the skew group algebra. By the result of Ginzburg\, this crepan
 t resolution is Morita equivalent to the Jacobian algebra of the McKay qui
 ver equipped with a canonical potential. We will discuss refined DT invari
 ants of such Jacobian algebras for the cases of finite subgroups of SL2 an
 d SO3\, where the quotient singularity admits a small crepant resolution a
 nd the McKay quiver is symmetric.\n\nhttps://us02web.zoom.us/j/87160036709
