Resumen de Bounding the orders of finite subgroups

Ian J. Leary, Brita E. A. Nucinkis

• We give homological conditions on groups such that whenever the conditions hold for a group $G$, there is a bound on the orders of finite subgroups of $G$. This extends a result of P. H. Kropholler. We also suggest a weaker condition under which the same conclusion might hold.
