F-Signature of Affine Toric Varieties (1110.0552v2)
Published 4 Oct 2011 in math.AC and math.AG
Abstract: We express the F-signature of the coordinate ring of an affine toric variety as the volume of a certain polytope, generalizing a formula of Watanabe and Yoshida. We also compute the F-signature of pairs and triples of a toric singularity.
