A finite purely quantum group would be a finite dimensional Hopf C\*-algebra (Kac algebra) K such that the unitary integral fusion category Rep(K) is not weakly group-theoretical, and admits no such fusion subcategory other than the trivial one. This talk will expose the first results in the quest of such an object, through joint works with Zhengwei Liu, Yunxiang Ren and Jinsong Wu, involving subfactor planar algebras, quantum Fourier analysis and fusion categories. **Additional Ways to Join** Join by telephone (use any number to dial in) +1 929 436 2866 +1 312 626 6799 +1 669 900 6833 400 669 9381 China Toll-free International numbers available: [https://harvar](https://harvard.zoom.us/u/aclg6kOggb)[d.zoom.us/u/aclg6kOggb](https://harvard.zoom.us/u/aclg6kOggb) One tap mobile: +19294362866,,779283357# US (New York) Join by SIP conference room system Meeting ID: 779 283 357 <779283357@zoomcrc.com> **Attachments** --- Attachments- [ picture\_as\_pdf Flyer.pdf ](/sites/g/files/omnuum6611/files/mathpicture/files/palcoux_seminar_october_27_2020updated.pdf) --- Share on:- [ Facebook ](#) - [ Twitter ](#) - [ Linkedin ](#) Save: [ Add to calendar calendar\_today ](https://mathpicture.fas.harvard.edu/node/1534150/event-feed.ics) Copy link link
