Mutations of Laurent Polynomials and Flat Families with Toric Fibers
We give a general criterion for two toric varieties to appear as fibers in a flat family over P^1. 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.
