Abstract

Dolgachev proves that the ring naturally associated to a generic Laurent polynomial in d variables, d≥ 4, is factorial (Dolgachev, 1980, 1981 [4,5]) (for any field k). We prove a sufficient condition for the ring associated to a very general complex Laurent polynomial in d= 3 variables to be Q-factorial. © 2011 Elsevier B.V.
