Mutations of Laurent Polynomials and Flat Families with Toric Fibers

Published 21 May 2012 in math.AG | (1205.4664v3)

Abstract: We give a general criterion for two toric varieties to appear as fibers in a flat family over the projective line. We apply this to show that certain birational transformations mapping a Laurent polynomial to another Laurent polynomial correspond to deformations between the associated toric varieties.
