ON THE ORBITS OF A BOREL SUBGROUP IN ABELIAN IDEALS [PDF]

open access: yesTransformation Groups, 2016
Let $B$ be a Borel subgroup of a semisimple algebraic group $G$, and let $\mathfrak a$ be an abelian ideal of $\mathfrak b=Lie(B)$. The ideal $\mathfrak a$ is determined by certain subset $Δ_{\mathfrak a}$ of positive roots, and using $Δ_{\mathfrak a}$ we give an explicit classification of the $B$-orbits in $\mathfrak a$ and $\mathfrak a^*$.

Fitting ideals of class groups for CM abelian extensions [PDF]

open access: yesAlgebra & Number Theory, 2021
Let $K/k$ be a finite abelian CM-extension and $T$ a suitable finite set of finite primes of $k$. In this paper, we determine the Fitting ideal of the minus component of the $T$-ray class group of $K$, except for the $2$-component, assuming the validity ...

Abelian decomposition and Weyl symmetric effective action of SU(3) QCD

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We show how to calculate the effective potential of SU(3) QCD which tells that the true minimum is given by the monopole condensation. To do this we make the gauge independent Weyl symmetric Abelian decomposition of the SU(3) QCD which decomposes the ...

Solution to the presentation problem for powers of the augmentation ideal of torsion free and torsion abelian groups

open access: yes, 2004
This paper solves for torsion free and torsion abelian groups G the problem of presenting nth powers Δn(G) of the augmentation ideal Δ(G) of an integral group ring ZG, in terms of the standard additive generators of Δn(G).

On the higher Fitting ideals of Iwasawa modules of ideal class groups over real abelian fields [PDF]

open access: yes, 2011
Kurihara established a refinement of the minus-part of the Iwasawa main conjecture for totally real number fields by using the higher Fitting ideals [Ku].

Piranti Lunak Pengujian Struktur Matematika Grup, Ring, Field Berbasis Osp (Open Source Program)

open access: yesComTech, 2014
This design of a computer software is a development and continuation of the software made on the previous research (2009/2010). However, this further research developed and expanded the scopes of testing more on the Siclic Group, Isomorphism Group, Semi

Abelian ideals and amazing roots [PDF]

open access: yesInternational Journal of Mathematics, 2017
Let [Formula: see text] be a simple Lie algebra with a Borel subalgebra [Formula: see text]. To any long positive root [Formula: see text], one associates two ideals of [Formula: see text]: the abelian ideal [Formula: see text] and not necessarily abelian ideal [Formula: see text].

Ordered groups with greatest common divisors theory

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
An embedding (called a GCD theory) of partly ordered abelian group G into abelian l-group Γ is investigated such that any element of Γ is an infimum of a subset (possible non-finite) from G. It is proved that a GCD theory need not be unique.

Energy–pressure relation for low-dimensional gases

open access: yesNuclear Physics B, 2014
A particularly simple relation of proportionality between internal energy and pressure holds for scale-invariant thermodynamic systems (with Hamiltonians homogeneous functions of the coordinates), including classical and quantum – Bose and Fermi – ideal ...
