NSS and TAP properties in topological groups close to being compact

Dikran Dikranjan, Dmitri Shakhmatov, Jan Spěvák

We introduce a notion of productivity (summability) of sequences in a topological group G, parametrized by a given function f : N --> omega+1. The extreme case when f is the functi…

Convergent sequences in minimal groups

Dmitri Shakhmatov

A Hausdorff topological group G is minimal if every continuous isomorphism f : G --> H between G and a Hausdorff topological group H is open. Clearly, every compact Hausdorff group…
