SIAG/AG Early Career Prize for Paul Breiding! 
Freitag, 26. Februar 2021
We are very proud to announce that our group member Paul Breiding  will receive the Early Career Prize  of the SIAM Activity Group on Algebraic Geometry. The prize will be awarded at the SIAM Conference on Applied Algebraic Geometry  in August 2021.
Congratulations on this great achievement, Paul!
Paper on the eigenvalue problem in JEMS 
There is a nice Youtube-Video  available, which gives a short summary of the paper
"A stable, polynomial-time algorithm for the eigenpair problem" by Armentano, Beltrán, Bürgisser, Cucker and Shub
that appeared in the Journal of the European Mathematical Society.

Invariant Theory for Maximum Likelihood Estimation 
Dienstag, 05. Mai 2020
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 joint research project of our group member Philipp Reichenbach  and his collaborators Carlos Améndola (TU Munich), Kathlén Kohn (KTH Stockholm) and Anna Seigal (University of Oxford).
An Algebraic Geometry Perspective on Topological Data Analysis 
Montag, 27. Januar 2020
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 as a pdf-file .
3264 Conics in a Second 
Donnerstag, 09. Januar 2020
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!
Please consider the following pdf  for the full press release on this subject. It also contains a link to the article. For a website version, we refer to the following linked page  on the website of the Max Planck Institute for Mathematics in the Sciences, Leipzig.

Thematic Einstein Semester: Varieties, Polyhedra, Computation 
Donnerstag, 21. Februar 2019
In the winter term 2019/20 there will be a Thematic Einstein Semester on (Applied) Algebraic Geometry, called Varieties, Polyhedra, Computation.
As a preparation there will be several courses and seminars at FU, HU and TU in the summer semester 2019. In particular, at TU Berlin the three lectures Real Algebra , Condition: The Geometry of Numerical Algorithms  and Variations on Bezout's theorem  as well as the software seminar Numerical Nonlinear Algebra  will be offered. Moreover, right before the start of the winter term there will be a fall school and an opening conference.
We are very much looking forward to this exciting program, that shall intensify the collaboration of the three Berlin universities in (Applied) Algebraic Geometry. Please stay tuned via the homepage  of the Thematic Einstein Semester.

The workshop "Complexity of Numerical Computation: A workshop in honor of Felipe Cucker" (or simply Felipe's Fest) will take place in Berlin from the 19th to the 23rd of August 2019. Colleagues and friends of Felipe Cucker will celebrate his 60th birthday presenting talks on the complexity of numerical computation and related topics. Additionally, the conference will have a lecture by Felipe on art and mathematics and an exhibition of the art project Approximation Theory in which Felipe took part. Every person in Berlin with an interest in mathematics is welcome to attend the conference. More information in this link .
This workshop is organized by Peter Bürgisser, Teresa Krick, Javier Peña and Steve Smale and will be funded by the Einstein Foundation Berlin and the European Research Council (ERC) (agreement grant No 787840).
