FRG Workshop on Discrete Shapes
Davis California, September 20 - 22, 2019
Joel Hass (University of California,
Davis), Patrice Koehl (University of California, Davis), Feng Luo
(Rutgers University, New Brunswick), David Glickenstein (University of
Arizona), Tianqi Wu (Harvard University)
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.
Abstracts of the talks, as well as posted slides and associated materials.
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
All talks will be held in Room 1147 of the Mathematics Sciences
Building on the UC Davis campus.
There are limited funds available for financial support of
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.
