On One Class of the Infinite Non-Abelian Groups
We present some properties of one class of the infinite non-abelian groups. We deal with a generalization of the INH and KI groups. Our main results are Theorem 1, 2, 3 and Theorem 4.

Uniformly exponential growth and mapping class groups of surfaces [PDF]
We show that the mapping class group (as well as closely related groups) of an orientable surface with finitely generated fundamental group has uniformly exponential growth.

Trees and mapping class groups [PDF]
There is a forgetful map from the mapping class group of a punctured surface to that of the surface with one fewer puncture. We prove that finitely generated purely pseudo-Anosov subgroups of the kernel of this map are convex cocompact in the sense of B.

Enumerating finite class-2-nilpotent groups on 2 generators [PDF]
We compute the numbers g(n,2,2) of nilpotent groups of order n, of class atmost 2 generated by at most 2 generators, by giving an explicit formula for theDirichlet generating function \sum_{n=1}^\infty g(n,2,2)n^{-s}

Every abelian group is a class group [PDF]
Let T be the set of minimal primes of a Krull domain A. If S is a subset of T9 we form B = n AP for PeS and study the relation of the class group of B to that of A. We find that the class group of B is always a homomorphic image of that of A. We use this type of construction to obtain a Krull domain with specified class group and then alter such a ...

In a paper by Polimeni [3] the concept of a c-group was introduced. A group is called a c-group if and only if every subnormal subgroup is characteristic. His paper claims to characterize finite soluble c-groups, which we will call fsc-groups. There are some errors in this paper; see the forthcoming review by K. W. Gruenberg in Mathematical Reviews.

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.

$p$-groups with maximal elementary abelian subgroups of rank $2$ [PDF]
Let p be an odd prime number and G a finite p-group. We prove that if the rank of G is greater than p, then G has no maximal elementary abelian subgroup of rank 2.

The dental, skeletal, and soft-tissue characteristics of a particular malocclusion can differ based on ethnicity, race, age, sex and geographical location with Class II malocclusion being one of the most prevalent malocclusions encountered in orthodontic

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.
