# Online Seminar: Feng Xu (University of California, Riverside), Rigorous results about Relative entropy in QFT #### calendar\_today Date and Time **May 25, 2021** 10:00AM - 10:00AM EDT #### pin\_drop Location **Zoom** **Location:** Zoom **Time:** Tuesday, 10:00 AM (Eastern US), 15:00 (UK/Eire), 16:00 (Central Europe), 22:00 (China) **Title:** Rigorous results about Relative entropy in QFT **Abstract:** We will present some rigorous results about Relative entropy in QFT, motivated in part by recent physicists’ work which however depends on heuristic arguments such as introducing cut off and using path integrals. In the particular case of CFT, we will discuss interesting relations between relative entropy, central charge and global dimension of conformal net. **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- [ picture\_as\_pdf 2021-05-25\_feng\_xu\_seminar\_announcement.pdf ](/sites/g/files/omnuum6611/files/mathpicture/files/2021-05-25_feng_xu_seminar_announcement.pdf) --- Share on:- [ Facebook ](#) - [ Twitter ](#) - [ Linkedin ](#) Save: [ Add to calendar calendar\_today ](https://mathpicture.fas.harvard.edu/node/1590339/event-feed.ics) Copy link link
