Solitary quotients of finite groups

Marius Tărnăuceanu (2012)

Open Mathematics

Similarity:

We introduce and study the lattice of normal subgroups of a group G that determine solitary quotients. It is closely connected to the well-known lattice of solitary subgroups of G, see [Kaplan G., Levy D., Solitary subgroups, Comm. Algebra, 2009, 37(6), 1873–1883]. A precise description of this lattice is given for some particular classes of finite groups.

On strong uniform dimension of locally finite groups

A. Sakowicz (2003)

Colloquium Mathematicae

Similarity:

We give the description of locally finite groups with strongly balanced subgroup lattices and we prove that the strong uniform dimension of such groups exists. Moreover we show how to determine this dimension.

On uniform dimensions of finite groups

J. Krempa, A. Sakowicz (2001)

Colloquium Mathematicae

Similarity:

Let G be any finite group and L(G) the lattice of all subgroups of G. If L(G) is strongly balanced (globally permutable) then we observe that the uniform dimension and the strong uniform dimension of L(G) are well defined, and we show how to calculate these dimensions.
