Local-global invariants of finite and infinite groups: around Burnside from another side
Abstract
This expository essay is focused on the Shafarevich-Tate set of a group G. Since its introduction for a finite group by Burnside, it has been rediscovered and redefined more than once. We discuss its various incarnations and properties as well as relationships (some of them conjectural) with other local-global invariants of groups.
