Large characteristic subgroups of surface groups not containing any simple loops

We determine the largest (i.e. smallest index) characteristic subgroup of surface groups not containing any simple loops.

Characteristic properties of large subgroups in primary abelian groups

Suppose G is an arbitrary additively written primary abelian group with a fixed large subgroup L. It is shown that G is (a) summable; (b) σ -summable; (c) a Σ-group; (d) pω+1-projective only when so is L. These claims extend results of such a kind obtained by Benabdallah, Eisenstadt, Irwin and Poluianov, Acta Math. Acad. Sci. Hungaricae (1970) and Khan, Proc. Indian Acad. Sci. Sect. A (1978).

Characteristic Subgroups of Finite Abelian Groups

We consider the question: When do two finite abelian groups have isomorphic lattices of characteristic subgroups? An explicit description of the characteristic subgroups of such groups enables us to give a complete answer to this question in the case where at least one of the groups has odd order. An “exceptional” isomorphism, which occurs between the lattice of characteristic subgroups of Zp ×...

Surface Subgroups of Graph Groups

Given a graph T , define the group Fr to be that generated by the vertices of T, with a defining relation xy — yx for each pair x, y of adjacent vertices of T. In this article, we examine the groups Fr, where the graph T is an H-gon, (n > 4). We use a covering space argument to prove that in this case, the commutator subgroup Ff contains the fundamental group of the orientable surface of genus ...

Classification of finite simple groups whose Sylow 3-subgroups are of order 9

In this paper, without using the classification of finite simple groups, we determine the structure of  finite simple groups whose Sylow 3-subgroups are of the order 9. More precisely, we classify finite simple groups whose Sylow 3-subgroups are elementary abelian of order 9.
