Enumerating finite class-2-nilpotent groups on 2 generators [PDF]
, 2009 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}

Fukaya categories of surfaces, spherical objects and mapping class groups
Forum of Mathematics, Sigma, 2021 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]
Proceedings of the Estonian Academy of Sciences, 2010 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.

Class-preserving Coleman automorphisms of some classes of finite groups
Open Mathematics, 2022 The normalizer problem of integral group rings has been studied extensively in recent years due to its connection with the longstanding isomorphism problem of integral group rings.

Research on a Class of Special Quasi TA-Neutrosophic Extended Triplet: TA-Groups [PDF]
Neutrosophic Sets and Systems, 2023 Tarski associative groupoid (TA-groupoid) and Tarski associative neutrosophic extended triplet groupoid (TA-NET-groupoid) are two interesting structures in non-associative algebra. In this paper, a new concept of TA-group is proposed based on TA-groupoid,

$p$-groups with maximal elementary abelian subgroups of rank $2$ [PDF]
, 2010 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.

On the Class Group and the Local Class Group of a Pullback
Journal of Algebra, 1996 Let \(M\) be a non-zero maximal ideal of an integral domain \(T\), \(k=T/M\), \(\varphi: T\to k\) the natural homomorphism, and \(D\) a proper subring of \(k\). Let \(R\) be the pullback \[ \begin{tikzcd} R \ar[r] \ar[d] & D\ar[d] \\ T\ar[r,"\varphi"'] & k=T/M \quad .

Every abelian group is a class group [PDF]
Pacific Journal of Mathematics, 1966 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 ...

Journal of the Australian Mathematical Society, 1969 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.
