Quantification pour les paires symétriques et diagrammes de Kontsevich

Alberto S. Cattaneo, Charles Torossian (2008)

Annales scientifiques de l'École Normale Supérieure

In this article we use the expansion for biquantization described in [7] for the case of symmetric spaces. We introduce a function of two variables E ( X , Y ) for any symmetric pairs. This function has an expansion in terms of Kontsevich’s diagrams. We recover most of the known results though in a more systematic way by using some elementary properties of this E function. We prove that Cattaneo and Felder’s star product coincides with Rouvière’s for any symmetric pairs. We generalize some of Lichnerowicz’s...

Quantised 𝔰𝔩 2 -differential algebras

Andrey Krutov, Pavle Pandžić (2024)

Archivum Mathematicum

We propose a definition of a quantised 𝔰𝔩 2 -differential algebra and show that the quantised exterior algebra (defined by Berenstein and Zwicknagl) and the quantised Clifford algebra (defined by the authors) of  𝔰𝔩 2 are natural examples of such algebras.

Quantization of Drinfeld Zastava in type A

Michael Finkelberg, Leonid Rybnikov (2014)

Journal of the European Mathematical Society

Drinfeld Zastava is a certain closure of the moduli space of maps from the projective line to the Kashiwara flag scheme of the affine Lie algebra 𝔰𝔩 ^ n . We introduce an affine, reduced, irreducible, normal quiver variety Z which maps to the Zastava space bijectively at the level of complex points. The natural Poisson structure on the Zastava space can be described on Z in terms of Hamiltonian reduction of a certain Poisson subvariety of the dual space of a (nonsemisimple) Lie algebra. The quantum Hamiltonian...

Quantization of Poisson Hamiltonian systems

Chiara Esposito (2015)

Banach Center Publications

In this paper we recall the concept of Hamiltonian system in the canonical and Poisson settings. We will discuss the quantization of the Hamiltonian systems in the Poisson context, using formal deformation quantization and quantum group theories.

Quantization of semisimple real Lie groups

Kenny De Commer (2024)

Archivum Mathematicum

We provide a novel construction of quantized universal enveloping * -algebras of real semisimple Lie algebras, based on Letzter’s theory of quantum symmetric pairs. We show that these structures can be ‘integrated’, leading to a quantization of the group C * -algebra of an arbitrary semisimple algebraic real Lie group.

Quantized semisimple Lie groups

Rita Fioresi, Robert Yuncken (2024)

Archivum Mathematicum

The goal of this expository paper is to give a quick introduction to q -deformations of semisimple Lie groups. We discuss principally the rank one examples of 𝒰 q ( 𝔰𝔩 2 ) , 𝒪 ( SU q ( 2 ) ) , 𝒟 ( SL q ( 2 , ) ) and related algebras. We treat quantized enveloping algebras, representations of 𝒰 q ( 𝔰𝔩 2 ) , generalities on Hopf algebras and quantum groups, * -structures, quantized algebras of functions on q -deformed compact semisimple groups, the Peter-Weyl theorem, * -Hopf algebras associated to complex semisimple Lie groups and the Drinfeld double, representations...
