Team Logic and Second-Order Logic

Team Logic and Second-Order Logic
Team logic is a new logic, introduced by Väänänen [11], extending dependence logic by classical negation. Dependence logic adds to first-order logic atomic formulas expressing functional dependence of variables on each other. It is known that on the level of sentences dependence logic and team logic are equivalent with existential secondorder logic and full second-order logic, respectively. In this article we show that, in a sense that we make explicit, team logic and secondorder logic are also equivalent with respect to open formulas. A similar earlier result relating open formulas of dependence logic to the negative fragment of existential second-order logic was proved in [7].
