Fully inert subgroups of torsion-complete p-groups
Journal of Algebra, 2020 A subgroup \(H\) of an abelian group \(G\) is called fully inert if the quotient \((H+\phi(H))/H\) is finite for every endomorphism \(\phi\) of \(G\). This is a common generalization of the notions of fully invariant, finite and finite-index subgroups.

Torsion classes in the cohomology of congruence subgroups [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 1989 For any prime number p, let Γn, p denote the congruence subgroup of SLn(ℤ) of level p, i.e. the kernel of the surjective homomorphism fp: SLn(ℤ) → SLn(p) induced by the reduction mod p (Fp is the field with p elements). We defineusing upper left inclusions Γn, p ↪ Γn+1, p.

On Pro-$p$ Cappitt Groups with finite exponent
Comptes Rendus. MathématiqueA pro-$p$ Cappitt group is a pro-$p$ group $G$ such that $\tilde{S}(G) = \overline{ \langle L \leqslant _c G \:|\, L \ntriangleleft G \rangle }$ is a proper subgroup (i.e. $\tilde{S}(G) \ne G$).

Non metrizable topologies on Z with countable dual group.
Applied General Topology, 2017 In this paper we give two families of non-metrizable topologies on the group of the integers having a countable dual group which is isomorphic to a infinite torsion subgroup of the unit circle in the complex plane.

The torsion in symmetric powers on congruence subgroups of Bianchi groups
Transactions of the American Mathematical Society, 2019 In this paper we prove that for a fixed neat principal congruence subgroup of a Bianchi group the order of the torsion part of its second cohomology group with coefficients in an integral lattice associated with the m m th symmetric power of the standard representation of SL 2 (

Nielsen realization for infinite-type surfaces
, 2020 Given a finite subgroup G of the mapping class group of a surface S, the Nielsen realization problem asks whether G can be realized as a finite group of homeomorphisms of S.

The Two-Generator Subgroups of One-Relator Groups with Torsion [PDF]
Transactions of the American Mathematical Society, 1977 The main aim of this paper is to show that every two-generator subgroup of any one-relator group with torsion is either a free product of cyclic groups or is a one-relator group with torsion. This result is proved by using techniques for reducing pairs of elements in certain HNN groups. These techniques not only apply to one-relator groups with torsion
