Öğe Uniformity of the meager ideal and maximal cofinitary groups(Academic Press Inc., 2000-10-01) Zhang, YiWe prove that every maximal cofinitary group has size at least the cardinality of the smallest non-meager set of reals. We also provide a consistency result saying that the spectrum of possible cardinalities of maximal cofinitary groups may be quite arbitrary. © 2000 Academic Press.
