Algebra, Geometry and Computation at CWI


Supported by a Veni grant from the Netherlands Organisation for Scientific Research (NWO).

On Thursday March 9, 2023, we held a seminar day on Algebra, Geometry and Computation at CWI, Amsterdam, Room L016. It featured a series of talks with title 'What is ...?', where the dots are filled in according to each of the speakers' expertise. Thanks to all nine speakers for the great talks!

Here is the list of speakers (in alphabetic order) with links to their websites: 

One of the topics will be 'Gibbs manifolds'. These sit inside the cone of positive semidefinite matrices, like the blue curve in the elliptope shown above.
