Imposing an extensional uniformity condition on a non-uniform circuit complexity class $\mathcal{C}$ means simply intersecting $\mathcal{C}$ with a uniform class $\mathcal{L}$. By contrast, the usual intensional uniformity conditions require that a resource-bounded machine be able to exhibit the circuits in the circuit family defining $\mathcal{C}$. We say that $(\mathcal{C},\mathcal{L})$ has the Uniformity Duality Propertyif the extensionally uniform class $\mathcal{C}\cap\mathcal{L}$ can be captured intensionally by means of adding so-called $\mathcal{L}$ -numerical predicatesto the first-order descriptive complexity apparatus describing the connection language of the circuit family defining $\mathcal{C}$.This paper exhibits positive instances and negative instances of the Uniformity Duality Property.
