The embedding of a cyclic permutable subgroup in a finite group. II [PDF]

, 2004
In two previous papers we established the structure of the normal closure of a cyclic permutable subgroup $A$ of a finite group, first when $A$ has odd order and second when $A$ has even order, but with an extra hypothesis that was unnecessary in the odd

Some local properties defining $T_0$-groups and related classes of groups [PDF]

, 2016
We call G a Hall_X -group if there exists a normal nilpotent subgroup N of G for which G/N' is an X -group. We call G a T_0-group provided G/Φ(G) is a T -group, that is, one in which normality is a transitive relation.

Permutable subnormal subgroups of finite groups [PDF]

, 2009
The aim of this paper is to prove certain characterization theorems for groups in which permutability is a transitive relation, the so called PT -groups.

A generalisation of a theorem of Wielandt [PDF]

, 2016
In 1974, Helmut Wielandt proved that in a finite group $G$, a subgroup $A$ is subnormal if and only if it is subnormal in every $\seq{A,g}$ for all $g\in G$.

Site 503: Eastern Equatorial Pacific [PDF]

, 1982
Our primary objective at Site 503 (Fig. 1) was to re- cover a complete, undisturbed Neogene and Quaternary section in the eastern equatorial Pacific. Site 503 is located near Site 83 in an area that contains an almost continuous pelagic record of the ...
