Schur's theorem and its relation to the closure properties of the non-abelian tensor product
arXiv:2601.19764 · doi:10.1017/prm.2018.150
Abstract
We show that the Schur multiplier of a Noetherian group need not be finitely generated. We prove that the non-abelian tensor product of a polycyclic (resp. polycyclic-by-finite) group and a Noetherian group, is a polycyclic (resp. polycyclic-by-finite) group. We also prove new versions of Schur's theorem.
