The cofinality of the infinite symmetric group and groupwise density
Published online by Cambridge University Press: 12 March 2014
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.
