Twisted bi-symplectic structure on Koszul twisted Calabi-Yau algebras

Xiaojun Chen, Alimjon Eshmatov, Farkhod Eshmatov +1

For a Koszul Artin-Schelter regular algebra (also called twisted Calabi-Yau algebra), we show that it has a "twisted" bi-symplectic structure, which may be viewed as a noncommutati…

Xiaojun Chen, Alimjon Eshmatov, Farkhod Eshmatov +1

Associated with each finite subgroup of there is a family of noncommutative algebras quantizing . Let be the group o…

Perverse Sheaves and Knot Contact Homology

Yuri Berest, Alimjon Eshmatov, Wai-kit Yeung

In this paper, which is mostly a research announcement, we give a new algebraic construction of knot contact homology in the sense of L. Ng [Ng05a]. For a link in $ {\mathbb R}…

The derived non-commutative Poisson bracket on Koszul Calabi-Yau algebras

Xiaojun Chen, Alimjon Eshmatov, Farkhod Eshmatov +1

Let be a Koszul (or more generally, -Koszul) Calabi-Yau algebra. Inspired by the works of Kontsevich, Ginzburg and Van den Bergh, we show that there is a derived non-commuta…

The group of unimodular automorphisms of is hopfian

Alimjon Eshmatov, Farkhod Eshmatov

Let be the group of unimodular automorphisms of . In the paper we prove two interesting results about this group. The first one is about absence of non-trivial fin…
