Abstract

We study the degree of elimination of imaginaries needed for the three main applications: to have canonical bases for types over models, to define strong types as types over algebraically closed sets and to have a Galois correspondence between definably closed sets B such that AB ⊆ acl(A) and closed subgroups of the Galois group Aut(acl(A)/A). We also characterize when the topology of the Galois group is the quotient topology. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract Working in the context of restricted forms of the Axiom of Choice, we consider the problem of splitting the ordinals below __λ__ of cofinality __θ__ into __λ__ many stationary sets, where __θ__ < __λ__ are regular cardinals. This is a continuation of [4] (© 2009 WILEY‐VCH Verlag GmbH &

## Abstract We show that the statement (K12) “separable, countably compact, regular spaces are Baire” is deducible from a strictly weaker form than AC, namely, CAC(ℝ) (the axiom of choice for countable families of non‐empty subsets of the real line ℝ). We also find some characterizations of the axi
