Geometrical McKay Correspondence for Isolated Singularities
نویسنده
چکیده
A Calabi-Yau manifold is a complex Kähler manifold with trivial canonical bundle. In the attempt to construct such manifolds it is useful to take into consideration singular CalabiYaus. One of the simplest singularities which can arise is an orbifold singularity. An orbifold is the quotient of a smooth Calabi-Yau manifold by a discrete group action which generically has fixed points. Locally such an orbifold is modeled on C/G, where G is a finite subgroup of SL(n,C).

Rings of Singularities
This paper is a slightly revised version of an introduction into singularity theory corresponding to a series of lectures given at the ``Advanced School and Conference on homological and geometrical methods in representation theory'' at the International Centre for Theoretical Physics (ICTP), Miramare - Trieste, Italy, 11-29 January 2010. We show how to associate to a triple of posit...
متن کاملA New Kind of McKay Correspondence From Non-Abelian Gauge Theories
The boundary chiral ring of a 2d gauged linear sigma model on a Kähler manifold X classifies the topological D-brane sectors and the massless open strings between them. While it is determined at small volume by simple group theory, its continuation to generic volume provides highly non-trivial information about the D-branes on X , related to the derived category D(X). We use this correspondence...
متن کاملSingular Mckay Correspondence for Normal Surfaces
We define the singular orbifold elliptic genus and E-function for all normal surfaces without strictly log-canonical singularities, and prove the analogue of the McKay correspondence in this setting. Our invariants generalize the stringy invariants defined by Willem Veys for this class of singularities. We show that the ability to define these invariants is closely linked to rigidity phenomena ...
