FRG Workshop on Discrete Shapes

Davis California, September 20 - 22, 2019

Workshop organizers:

Joel Hass (University of California, Davis), Patrice Koehl (University of California, Davis), Feng Luo (Rutgers University, New Brunswick), David Glickenstein (University of Arizona)

This workshop is part of the NSF FRG project: Geometric and Topological Methods for Analyzing Shapes.
The first half of the workshop will feature introductory talks aimed at graduate students and newcomers to the area. Boris Springborn and David Gu will each give two introductory talks. The remaining part will have both background and research talks. There will also be organized discussions of open problems and potential applications.


Boris Springborn and David Gu will each give two background lectures.
Additional background and research lectures will be given. A schedule is below.

Registration is free and open to everyone. If you are planning to attend, please register as soon as possible so that we can prepare appropriate amounts of food etc. Register by filling in the
Registration Form


All talks will be held in Room 1147 of the Mathematics Sciences Building on the UC Davis campus.

Financial Support:

There are limited funds available for financial support of participants. These are primarily intended for graduate students and early career researchers. Preference for financial support will be give to applications received by by June 15, 2019, but we will consider later requests as funds allow. Graduate students requesting support should request a couple of paragraphs from their advisor. Please send requests for travel support in an email to:
with the subject line: FRG Workshop Support Request.
To receive reimbursement for airline travel, the National Science Foundation requires that you must fly a US carrier.

Travel and Accomodations:

Please make your own arrangements for travel unless we contact you with other information. A list of local Davis hotels can be found here: Davis Hotels
