### Polytopes occurring in the McKay correspondence

**Algebra & Discrete Mathematics**

Speaker: | Diane Maclagan, Stanford |

Location: | 693 Kerr |

Start time: | Tue, Nov 25 2003, 2:10PM |

The study of the McKay correspondence originated in the work of McKay over 20 years ago comparing graphs arising from the representation theory and geometry of finite subgroups of SL(2,C). One recent aspect is the study of moduli of representations of the McKay quiver, an object defined by the representation theory of G. I will discuss the case where the group is abelian, where all the objects involved have concrete combinatorial interpretations in terms of polytopes. This is joint work with Alastair Craw and Rekha Thomas.
