Arity hierarchies

open access: yesAnnals of Pure and Applied Logic, 1996
For many extensions \(L\) of first-order logic considered for finite structures there is a natural notion of arity of a formula (e.g., the maximal arity of a bounded second-order variable in a formula of fixed-point logic). Denote by \(L^k\) the fragment of \(L\) consisting of the sentences of \(L\) of arity \(\leq k\).
