Dependence logic adds the concept of dependence to first order logic. That is, we may add new atomic formulas of the form

$= (x_1,x_2,\ldots,x_n,y)$

meaning that the values of $x_1,\ldots,x_n$ completely determine the value of $y$.

It “aims to establish a basic theory of dependence and independence underlying such seemingly unrelated subjects as causality, random variables, bound variables in logic, database theory, the theory of social choice, and even quantum physics” (from the abstract of Galliani, Väänänen 2014).

Team logic is a further extension of dependence logic by classical negation.
