MCKAY CORESPONDENCE IN QUASI-TORIC ORBIFOLDS

SAIBAL GANGULI

IMSc

McKay correspondence relates orbifold cohomology with the coho-
mology of a crepant resolution. This is a phenomenon in algebraic geometry. It
was proved for toric orbifolds by Batyrev and Dais in the nineties. In this talk we
present a similar correspondence for omnioriented quasitoric orbifolds. The inter-
esting feature is how we deal with the absence of an algebraic or analytic structure.
In a suitable sense, our correspondence is a generaliztion of the algebraic one.
