Dear Colleague,

We are writing to announce the Western Hemisphere Colloquium on Geometry 
and Physics (WHCGP).  This biweekly online colloquium features geometers and 
physicists presenting current research on a wide range of topics in the interface 
of the two fields. The talks are aimed at a broad audience. They will take place 
via Zoom on alternate Mondays at 3pm Eastern, noon Pacific, 4pm BRT. (There 
will be no lecture on May 25, Memorial Day in the USA.)  Each session features a 
60 minute talk, followed by 15 minutes for questions and discussion. You may 
join the meeting 15 minutes in advance. Questions and comments may be 
submitted to the moderator via the chat interface during the talk, or presented 
in person during the Q&A session. These colloquia will be recorded and will be 
available on the WHCGP website asap after the event.

The first two talks are:

  April 13, Edward Witten (IAS), Volumes and random matrices

  April 27, Kevin Costello (PI), Topological Strings, twistors, and Skyrmions

To receive Zoom links and further announcements, please subscribe to the 
WHCGP email list at:

Participants from anywhere in the world are welcome.

Apologies if you receive multiple copies of this message.

The organizing committee,

This message was sent to you via the Geometry List, which announces conferences in geometry and closely related areas to over 1600 mathematicians worldwide.

At http://listserv.utk.edu/archives/geometry.html there are many functions available, including checking the archives since November 2005, changing your e-mail address or preferences, and joining/leaving the list. If you have problems that cannot be resolved at this website, send a message to [log in to unmask]

Before sending an announcement, please carefully read the following. Any announcements that are *not* about conferences (e.g. those about jobs, journals, books, etc.) will be rejected by the moderator without comment. To announce a geometry or closely related conference, send the announcement (including a conference web site if possible) to [log in to unmask] The moderator cannot edit your message; list members will receive the announcement as an e-mail from you EXACTLY as you submitted it. For example, if your submission starts with "Please post this on the geometry list" then your conference announcement will also begin with that statement. In order to keep down the volume of e-mail, only TWO announcements per conference will be approved by the moderator. The "subject" of your message should include the name of the conference and the number (first or second) of the announcement, e.g. Gauss Memorial Lectures in Geometry: Second Announcement. Please check that your announcement (especially the website) is correct. Corrections will be approved only in the most critical situations, e.g. if corrected information is not available on the website. After submitting an announcement you may receive a message asking you to confirm your submission. This feature is designed to thwart the hundreds of machine-generated spam that are sent to the list and would otherwise have to be manually blocked by the moderator. If you do not see your announcement within 48 hours, please check the archives to see whether it was actually posted (i.e. you somehow missed seeing the post or are not subscribed with your current email address). If the announcement is not in the archive, search for a confirmation message that you may have missed (from listserv.utk.edu). If none of this solves the mystery, send a message to [log in to unmask]
