Cohomology of wheels on toric varieties

Alastair Craw, Alexander Quintero Velez

Published 2012-06-26, updated 2014-05-05Version 2

We describe explicitly the cohomology of the total complex of certain diagrams of invertible sheaves on normal toric varieties. These diagrams, called wheels, arise in the study of toric singularities associated to dimer models. Our main tool describes the generators in a family of syzygy modules associated to the wheel in terms of walks in a family of graphs.
