On maximal subformations of n-multiple Ω-foliated formations of finite groups [PDF]
Only finite groups are considered in the article. Among the classes of groups the central place is occupied by classes closed regarding homomorphic images and subdirect products which are called formations.

A Class of Frobenius Groups [PDF]
If a group contains two subgroups A and B such that every element of the group is either in A or can be represented uniquely in the form aba', a, a’ in A, b ≠ 1 in B, we shall call the group an independent ABA-group. In this paper we shall investigate the structure of independent ABA -groups of finite order.A simple example of such a group is the group

ON A CLASS OF SUPERSOLUBLE GROUPS [PDF]
AbstractA subgroup $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}H$ of a finite group $G$ is said to be S-semipermutable in $G$ if $H$ permutes with every Sylow $q$-subgroup of $G$ for ...

A Countable-Type Theorem for Uncountable Groups [PDF]
The aim of this paper is to develop a general construction method of finite series of a group G based on the existence of suitable finite series in the countable subgroups of G.

Rational Class Sizes and Their Implications for the Structure of Finite Groups [PDF]
This paper considers the implications of rational class sizes for the structure of finite groups. Ever since Itô introduced the notion of a conjugate type vector in 1953, the problem of unraveling the connections between the set of conjugacy class sizes ...

Fukaya categories of surfaces, spherical objects and mapping class groups
We prove that every spherical object in the derived Fukaya category of a closed surface of genus at least $2$ whose Chern character represents a nonzero Hochschild homology class is quasi-isomorphic to a simple closed curve equipped with a rank $1 ...

Finding a class of 2-groups; pp. 370–374 [PDF]
Let n ³ â¥3 be an integer and Cm denote a cyclic group of order m. All groups which can be presented as a semidirect products (C2n x C2n) âC4 are described. These groups are given by generators and defining relations.
