Real algebraic geometry and interactions, 06-10 Oct 2025
Some TENORS DCs (DC1 – Enrica Barrilli at Inria, DC3 – Sami Halaseh at LAAS-CNRS, DC5 – Matteo Bechere at University of Kosntanz) attended this event in October 2025 in Nice, France.

Workshop Bedlewo
We’d like to share news about a “summer” school run by Joachim Jelisiejew and Mateusz Michalek in November, in Bedlewo (near Poznan) under the auspices of Oberwolfach.
Geometry in Cryptography and Communication
Geometry in Cryptography and Communication held in Tromsø (Norway) in the week of October 6–10, 2025.
Secant varieties of Segre-Veronese varieties $\mathbb P^m\times\mathbb P^n$ embedded by $\mathcal O(1,2)$ are non-defective for $n\gg m^3$, $m\geq3$
By Matej Dolezalek (UKON) and Nikhil Ken (UNIFI) At the end of March, we finished our article on secant varieties of O(1,2) Segre-Veronese varieties. It is currently going through the submission process, and in the meantime, it is available as a preprint: arXiv:2503.21972 In the article, we prove that all secant…
SIAM AG Conference in Madison, Wisconsin
By Henri Linus Breloer (UiT)The SIAM conference in algebraic geometry took place in Madison, Wisconsin, this year. For this month’s newsletter, I would like to share my experience of attending the conference. It started in January, when I was given the opportunity to hold a talk at the conference, but…
Beyond Waring: Uncovering the Fine Structure of Symmetric Tensors
By Enrica Barrilli (Inria) Classical tensor decomposition—Waring’s model—seeks to express a symmetric tensor as a minimal sum of pure powers of linear forms. While elegant and foundational, this model is also inherently limited. In both geometry and applications, many tensors exhibit a far richer internal structure: multiplicities, tangent directions, and…
Geometry in Cryptography and Communication School
Geometry in Cryptography and Communication held in Tromsø (Norway) in the week of October 6–10, 2025.
Reading group on Ideals, Varieties, and Algorithms by Cox, Little, O’Shea
A tentative eight-week schedule with 16 sessions and a pdf of the book are available here: https://otps3141.github.io/reading_group.html Each session is lead by a speaker who presents the material or exercises for the day. Speakers will be assigned based on participants’ availability.
The first secondment in TENORS project
By Matej Dolezalek, University of Konstanz Since I happen to be the first person in the network to go on a secondment, I’d like to write a few words about my experience. I hope that my account may be of non-zero interest to someone and perhaps even an amusing point…
The start of DC3, DC4, DC7 in TENORS
Sami Halaseh, DC3 has been about a month into his PhD now at LAAS. Most of the administrative things have been taken care of and its nice to be able to focus on his work. He is still in the foundation building stage, but he quite enjoys that part. Everything…
