F U N D a M E N T a Mathematicae M-rank and Meager Groups

Abstract

Assume p∗ is a meager type in a superstable theory T . We investigate definability properties of p∗-closure. We prove that if T has < 2א0 countable models then the multiplicity rank M of every type p is finite. We improve Saffe’s conjecture. 0. Introduction. Throughout the paper, T is a superstable theory in a countable language L, and we work within a… (More)
