The second bounded cohomology of a group with infinitely many ends

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/152981We study the second bounded cohomology of an amalgamated free product of groups, and an HNN extension of a group. As an application, we have a group with infinitely many ends has infinite dimensional second bounded cohomology.Group TheoryThe second bounded cohomology of a group with infinitely many endstext
