We study the class# AC 0 of functions computed by constant-depth polynomial-size arithmetic circuits of unbounded fan-in addition and multiplication gates. No model-theoretic characterization for arithmetic circuit classes is known so far. Inspired by Immerman's characterization of the Boolean circuit class AC 0, we remedy this situation and develop such a characterization of# AC 0. Our characterization can be interpreted as follows: Functions in# AC 0 are exactly those functions counting winning strategies in first-order model checking games. A consequence of our results is a new model-theoretic characterization of TC 0, the class of languages accepted by constant-depth polynomial-size majority circuits.
