Peterfest: Geometry in Complexity and Computations

The conference Geometry in Complexity and Computations takes place at the University of Konstanz on September 21-23. This event celebrates Peter Bürgisser and his contributions to the field on the occasion of his 60th birthday.

Invited Talk by Peter Bürgisser at STACS 2021

On March 16, Peter Bürgisser will give an invited talk at the 38th International Symposium on Theoretical Aspects of Computer Science. He will speak about Optimization, Complexity and Invariant Theory, based on recent research with Cole Franks, Ankit Garg, Rafael Oliveira, Michael Walter and Avi Wigderson. The corresponding extended abstract /…

Invariant Theory for Maximum Likelihood Estimation

The case study Invariant Theory for Maximum Likelihood Estimation is published at the website of the University of Oxford, https://www.maths.ox.ac.uk/node/35937. It is based on a recent preprint (arXiv:2003.13662), that connects notions of stability from Invariant Theory with maximum likelihood estimation from (Algebraic) Statistics.
This is a…

An Algebraic Geometry Perspective on Topological Data Analysis

Our group member Paul Breiding recently wrote an article about topological data analysis from an algebraic-geometric point of view. It was published in  SIAM News, Issue January/February 2020. Please find in the following the linked online version of the article including a short demonstration video, as well as the corresponding issue of SIAM News…

3264 Conics in a Second

The article "3264 Conics in a Second" by our group member Paul Breiding and his co-authors Bernd Sturmfels and Sascha Timme was recently published in the Notices of the AMS (issue January 2020). Moreover, one image of the article is used prominently for the cover design!
