Abstract

Some groups are so discrete that abstract homomorphisms from many of the standard continuous topological groups to such a group always have open kernel. It was known classically that any homomorphism from a completely metrizable group to a free group has open kernel. I'll talk about the history of such results and give a plethora of new examples. Joint work with Greg Conner.
