Titre / Title: A Reiterman theorem for pseudovarieties of finite first-order structures
Abstract : We extend Reiterman's theorem to first-order structures: a classs of finite first-order structures is a pseudovariety if and only if it is defined by a set of identities in a certain relatively free profinite structure (pseusoidentities).
