On subnormal subgroups of linear groups

Siberian Mathematical Journal, 2008
Summary: We describe the subnormal subgroups of 2-dimensional linear groups over local and full rings in which 2 is invertible, as well as the subnormal subgroups of symplectic groups over local rings in which 2 is invertible.

Characters of subnormal subgroups ofM-groups

Archiv der Mathematik, 1984
By definition, a finite group G is called an M-group if each of its irreducible complex characters is induced from a linear character of a subgroup of G. In this paper several theorems are proved. The most important are Theorem 1: Let G be an M-group and let S be a subnormal subgroup of odd index in G.

Joins of almost subnormal subgroups

Archiv der Mathematik, 1989
A subgroup X of a group G is almost subnormal in G if X has finite index in some subnormal subgroup of G. Several sufficient conditions are given for a join of almost subnormal subgroups to be almost subnormal.

Conditions for subnormality of a join of subnormal subgroups

Mathematical Proceedings of the Cambridge Philosophical Society, 1982
The object of this paper is to prove a necessary and sufficient condition on two groups H, K for their join always to be subnormal in a group G whenever they are embedded subnormally in G.

Some congruences of subnormal subgroups

Rendiconti del Seminario Matematico e Fisico di Milano, 1995
Let \(G\) be a group having a finite composition series. Then the set \(R(G)\) of all subnormal subgroups of \(G\) is a sublattice of the lattice \(L(G)\) of all subgroups of \(G\). If \(\tau\) is an equivalence relation on the set \(R(G)\), the \textit{lower kernel} \(N_\tau\) of \(\tau\) is the subgroup generated by all elements of \(R(G)\) which are
