The cofinality of the infinite symmetric group and groupwise density

Research output: Contribution to journal › Article › peer-review

Abstract

We show that g ≤ c(Sym(ω)) where g is the groupwise density number and c(Sym(ω)) is the cofinality of the infinite symmetric group. This solves (the second half of) a problem addressed by Thomas.
