International audience; The third author noticed in his 1992 PhD Thesis [Sim92] that every regular tree language of infinite trees is in a class $\Game (D_n({\bf\Sigma}^0_2))$ for some natural number $n\geq 1$, where $\Game$ is the game quantifier. W

The Axiom of Projective Determinacy implies the existence of a universal set for every n ≥ 1. Assuming there exists a universal set. In ZFC there is a universal set for every α.
