A new algebraic method for the description of 2D nonlinear polynomial discrete systems is developed via so-called generalized mixed operators. These operators are a generalization of
-operators to include two-dimensional discrete polynomial systems containing cross products. Series of these operators are also introduced, and their invertibility is investigated. This description is applied to certain examples from control theory and nonlinear dynamics
