REVERSIBLE SKEW LAURENT POLYNOMIAL RINGS AND DEFORMATIONS OF POISSON AUTOMORPHISMS [PDF]

open access: yesJournal of Algebra and Its Applications, 2009
A skew Laurent polynomial ring S = R[x±1;α] is reversible if it has a reversing automorphism, that is, an automorphism θ of period 2 that transposes x and x-1 and restricts to an automorphism γ of R with γ = γ-1. We study invariants for reversing automorphisms and apply our methods to determine the rings of invariants of reversing automorphisms of the

Prime Ideals and Strongly Prime Ideals of Skew Laurent Polynomial Rings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
We first study connections between α-compatible ideals of R and related ideals of the skew Laurent polynomials ring R[x,x−1;α], where α is an automorphism of R.

Cremmer-Gervais cluster structure on SLn. [PDF]

open access: yesProc Natl Acad Sci U S A, 2014
We study natural cluster structures in the rings of regular functions on simple complex Lie groups and Poisson-Lie structures compatible with these cluster structures. According to our main conjecture, each class in the Belavin-Drinfeld classification of

Radicals of skew polynomial rings and skew Laurent polynomial rings

open access: yesJournal of Algebra, 2011
In this paper, \(R\) denotes an associative ring with identity, and \(\sigma\) stands for an automorphism of \(R\). \(W(R)\), \(L(R)\) and \(N(R)\) denote the Wedderburn radical, the Levitzki radical and the upper nil radical of \(R\), respectively. An ideal \(I\) of \(R\) is called a \(\sigma\)-ideal if \(\sigma(I)\subseteq I\).

CHARACTERIZATIONS OF ELEMENTS IN PRIME RADICALS OF SKEW POLYNOMIAL RINGS AND SKEW LAURENT POLYNOMIAL RINGS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2011
We show that the -prime radical of a ring R is the set of all strongly -nilpotent elements in R, where is an automorphism of R. We observe some conditions under which the -prime radical of R coincides with the prime radical of R. Moreover we characterize elements in prime radicals of skew Laurent polynomial rings, studying (; 1 )- (semi)primeness of ...

Primitive skew Laurent polynomial rings [PDF]

open access: yesGlasgow Mathematical Journal, 1978
In [8] the author studied the question of the primitivity of an Ore extension R[x, δ], where δ is a derivation of the ring R. If a is an automorphism of R then it can be shown that R[x, α] is primitive if the following conditions are satisfied: (i) no power αsS ≥ 1, of α is inner; (ii) the only ideals of R invariant under α are 0 and R.

Secants of minuscule and cominuscule minimal orbits [PDF]

open access: yes, 2014
We study the geometry of the secant and tangential variety of a cominuscule and minuscule variety, e.g. a Grassmannian or a spinor variety. Using methods inspired by statistics we provide an explicit local isomorphism with a product of an affine space ...

PRIME RADICALS OF SKEW LAURENT POLYNOMIAL RINGS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2005
Summary: Let \(R\) be a ring with an automorphism \(\sigma\). An ideal \(I\) of \(R\) is a `\(\sigma\)-ideal' of \(R\) if \(\sigma(I)=I\). A proper ideal \(P\) of \(R\) is a `\(\sigma\)-prime ideal' of \(R\) if \(P\) is a \(\sigma\)-ideal of \(R\) and for \(\sigma\)-ideals \(I\) and \(J\) of \(R\), \(IJ\subseteq P\) implies that \(I\subseteq P\) or \(J\
