Wadge degrees of $\Delta^0_2$ omega-powers
<|reference_start|>Wadge degrees of $\Delta^0_2$ omega-powers: We provide, for each natural number $n$ and each class among $D_n(\Sigma^0_1)$, $\bar D_n(\Sigma^0_1)$ and $D_{2n+1}(\Sigma^0_1)\oplus\bar D_{2n+1}(\Sigma^0_1)$, a regular language whose associated omega-power is complete for this class.<|reference_end|>
