Complex analytic quantum groups

Abstract: We discuss a missing link in quantum group theory - quantum analogues of complex Lie groups. As such analogues, I propose to take topological Hopf algebras with a finiteness condition (holomorphically finitely generated or HFG for short). This approach is not directly related to C*-algebraic quantum groups (at least for now) but is an alternative view. Nevertheless, the topic seems to offer a wide range of research opportunities.

Our focus is on examples, such as analytic forms of some classical quantum groups (a deformation of a solvable Lie group and Drinfeld-Jimbo algebras). I also present some general results: 1) the category of Stein groups is anti-equivalent to the category of commutative Hopf HFG algebras; 2) If $G$ is a compactly generated Lie group, the cocommutative topological Hopf algebra $\widehat{A(G)}$ (naturally associated with $G$) is HFG. When in addition, $G$ is connected linear, the structure of $\widehat{A(G)}$ can be described explicitly.

I also plan to discuss briefly holomorphic duality in the sense of Akbarov (which is parallel to Pontryagin duality).

Noncommutative Geometry in NYC

Series comments: Noncommutative Geometry studies an interplay between spatial forms and algebras with non-commutative multiplication. Our seminar welcomes talks in Number Theory, Geometric Topology and Representation Theory linked to the context of Operator Algebras. All talks are kept at the entry-level accessible to the graduate students and non-experts in the field. To join us click sju.webex.com/meet/nikolaei (5 min in advance) and igor DOT v DOT nikolaev AT gmail DOT com to subscribe/unsubscribe for the mailing list, to propose a talk or to suggest a speaker. Pending speaker's consent, we record and publish all talks at the hyperlink "video" on speaker's profile at the "Past talks" section. The slides can be posted by providing the organizers with a link in the format "myschool.edu/~myfolder/myslides.pdf". The duration of talks is 1 hour plus or minus 10 minutes.
