Bicyclic commutator quotients with one non-elementary component

Daniel Mayer (2023)

Mathematica Bohemica

For any number field $K$ with non-elementary $3$ -class group ${Cl}_{3} (K) ≃ C_{3^{e}} \times C_{3}$ , $e \geq 2$ , the punctured capitulation type $ϰ (K)$ of $K$ in its unramified cyclic cubic extensions $L_{i}$ , $1 \leq i \leq 4$ , is an orbit under the action of $S_{3} \times S_{3}$ . By means of Artin’s reciprocity law, the arithmetical invariant $ϰ (K)$ is translated to the punctured transfer kernel type $ϰ (G_{2})$ of the automorphism group $G_{2} = Gal (F_{3}^{2} (K) / K)$ of the second Hilbert $3$ -class field of $K$ . A classification of finite $3$ -groups $G$ with low order and bicyclic commutator quotient $G / G^{'} ≃ C_{3^{e}} \times C_{3}$ , $2 \leq e \leq 6$ , according to the algebraic invariant...

Breaking points in the poset of conjugacy classes of subgroups of a finite group

Marius Tărnăuceanu (2019)

Czechoslovak Mathematical Journal

We determine the finite groups whose poset of conjugacy classes of subgroups has breaking points. This leads to a new characterization of the generalized quaternion $2$ -groups. A generalization of this property is also studied.

Central sequences in the factor associated with Thompson’s group $F$

Paul Jolissaint (1998)

Annales de l'institut Fourier

We prove that the type ${II}_{1}$ factor $L (F)$ generated by the regular representation of $F$ is isomorphic to its tensor product with the hyperfinite type ${II}_{1}$ factor. This implies that the unitary group of $L (F)$ is contractible with respect to the topology defined by the natural Hilbertian norm.
