Polytopes occurring in the McKay correspondence

Description
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.
