Title: G-Hilb and crepant resolutions of certain abelian orbifolds in dimension 4
Date: Tue, Mar 06, 2018, 15:30 - 17:00
Place: Seminar Room B
Abstract: Let G ╲subset Sl(4,╲CC) be a maximal diagonal subgroup of exponent r. In this talk, I will describe the G-Hilbert scheme G-Hilb(C4) through its toric fan and show how it can be used to construct "special" crepant resolutions of the quotient variety ╲CC^4/ G. I will also discuss whether these crepant resolutions could be interpreted as the moduli spaces ╲mathcal{M}_╲theta of ╲theta-stable G-constellations.
