The Coefficient-Choosing Game

Number Theory 2017-10-13 v2

Abstract

Let DD be an integral domain. Two players, Nora and Wanda, alternately choose coefficients from DD for a polynomial of degree dd. When they are done, if the polynomial has a root in the field of fractions of DD, then Wanda wins. If not, then Nora wins. We determine, for many DD, who wins this game.
