Our model is based on the Chevalley-type multiplication formula for KT(G/B) due to the first author and Postnikov; this formula is stated using certain operators defined in terms of so-called alcove paths (and the corresponding affine Weyl group).

Our model is derived using a type-independent and concise approach. Thus, the Nichols algebra B W provides a model for the coinvariant algebra, Schubert calculus and (in the crystallographic case) cohomology of the flag manifold for an arbitrary Coxeter group W in the same sense as the Fomin–Kirillov algebras E from [FK] provide such a model for W = by: Nichols-Woronowicz algebra model for Schubert calculus 3 ‘super’ Nichols-Woronowicz algebras Λw(W), which control the noncommutative geometry of Weyl groups W, are considered.

The structure of the paper is as follows. In Section 1 we recall basic facts about Coxeter groups, their root systems, coinvariant algebras and Schubert polynomials. In other words, we construct the “Nichols-Woronowicz algebra model” for the Grothendieck calculus on Weyl groups of classical type or type G2, providing a Author: Yuri Bazlov.

Bazlov [1]. One of the main motivations and purposes of the present paper is to construct the Nichols-Woronowicz model for the Grothendieck Calculus for classical Weyl groups and G2,as well. Weyl groups are inﬁnite dimensional. We establish the relationship between Fomin-Kirillov algebra En and Nichols algebra B(O (1,2),ǫ⊗sgn) of transposition over sym-metry group by means of quiver Hopf algebras.

We generalize FK algebra. The characteristic of ﬁniteness of Nichols algebras in thirteen ways and of FK algebras En in nine ways. Affine Schubert polynomials are defined by using divided difference operators, generalizing those operators used to define Schubert polynomials, so that Schubert polynomials are special cases of affine Schubert by: 1.

which means that Weyl quantization satisﬁes Dirac’s quantization condition up to higher orders in ~ or in other words that the algebra of pseudodiﬀerential operators is a deformation of the algebra of symbols in direction of the Poisson bracket.

The nilCoxeter algebra and its action on the coinvariant algebra by divided difference operators Author: Christoph Bärligea. In abstract algebra, the Weyl algebra is the ring of differential operators with polynomial coefficients (in one variable), namely expressions of the form ∂ + − ∂ − + ⋯ + ∂ + ().More precisely, let F be the underlying field, and let F[X] be the ring of polynomials in one variable, X, with coefficients in each f i lies in F[X].

∂ X is the derivative with respect to X. Abstract. Nichols algebras, Hopf algebras in braided categories with distinguished properties, were discovered several times.

They appeared for the first time in the thesis of W. Nichols [], aimed to construct new examples of Hopf this same paper, the small quantum group \(u_q(sl_3)\), with q a primitive cubic root of one, was by: In mathematics, in particular the theory of Lie algebras, the Weyl group of a root system Φ is a subgroup of the isometry group of the root ically, it is the subgroup which is generated by reflections through the hyperplanes orthogonal to the roots, and as such is a finite reflection ctly, Weyl groups are finite Coxeter groups, and are important.

Weyl, is the fact that real Hamiltonians get quantized by (formally) self-adjoint that the classical quantization of the Hamiltonian is given by the operator acting on functions by.

The Weyl algebra can also be constructed as an iterated Ore extension of the polynomial ring \(R[x_1, x_2, \ldots, x_n]\) by adding \(x_i\) at each step. It can also be seen as a quantization of the symmetric algebra \(Sym(V)\), where \(V\) is a finite dimensional vector space over a field of characteristic zero, by using a modified Groenewold.
