    Q-factorial Laurent rings
    (SISSA, 2011-08-20) Bruzzo, Ugo; Grassi, Antonella; Mathematics; Mathematical Physics
    Dolgachev proved that, for any field k, the ring naturally associated to a generic Laurent polynomial in d variables, $d \geq 4$, is factorial. We prove a sufficient condition for the ring associated to a very general complex Laurent polynomial in d=3 variables to be Q-factorial.
