Degenerations and orbits in finite abelian groups

Journal of Combinatorial Theory, Series A, 2011
A notion of degeneration of elements in groups is introduced. It is used to parametrize the orbits in a finite abelian group under its full automorphism group by a finite distributive lattice. A pictorial description of this lattice leads to an intuitive self-contained exposition of some of the basic facts concerning these orbits, including their ...

Abelian subgroups of finite 𝑝-groups

, 1972
Information is obtained about the order of maximal abelian subgroups of central powers and crown products of finite p p -groups. This is used to construct groups with “small” maximal abelian subgroups.

Crepant resolutions and A-Hilbert schemes in dimension four [PDF]

The aim of this thesis is to improve our understanding of when crepant resolutions exist in dimension four. In three dimensions [BKR01] proved that for any finite subgroup G ⊂ SL(3,C) the G-Hilbert scheme G-Hilb(C3) gives a crepant resolution of the ...

On the structure of finite loop capable Abelian groups [PDF]

, 2007
summary:Loop capable groups are groups which are isomorphic to inner mapping groups of loops. In this paper we show that abelian groups $C_p^{k}\times C_p\times C_p$, where $k\geq 2$ and $p$ is an odd prime, are not loop capable groups.

The Chebotarev invariant of a direct product of non-abelian finite simple groups [PDF]

openL'obiettivo di questa tesi è quello di derivare limiti superiori per il valore atteso del numero di elementi random necessari per generare e per generare invariabilmente un prodotto diretto di gruppi semplici, finiti e non abeliani.

Fuzzy Internal Direct Product

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2019
The purpose of this research is to show a constructive method for using known fuzzy groups as building blocks to form more fuzzy subgroups. As we shall describe employing this procedure with the fuzzy generating subgroups give us a large class of ...

Tiles with no spectra

, 2006
We exhibit a subset of a finite Abelian group, which tiles the group by translation, and such that its tiling complements do not have a common spectrum (orthogonal basis for their L-2 space consisting of group characters).
