The University or Nebraska-Lincoln and CIMAT are co-organizing an international REU in Commutative Algebra, to be held at CIMAT, in Guanajuato, Mexico, in Summer 2025.

American citizens and permanent US residents will be supported with funds from the National Science Foundation (NSF), while Mexican citizens or residents in Mexico will be supported with funds from the Consejo Nacional de Humanidades, Ciencias, y Tecnologías (CONAHCYT). Participants will receive a stipend for the duration of the program and assistance with housing and travel.

More information, including how to apply, can be found on the REU website.

Iowa State University is hiring a postdoc in commutative algebra to work with Prof. Jason McCullough. More details are in the mathjobs ad.

Aida Maraj’s group Algebra in Data Analysis has a special interest in candidates with background in algebraic geometry, commutative algebra and combinatorics that are enthusiastic about interdisciplinary research with statistics and biology. She is happy to answer questions via email at maraj@mpi-cbg.de.

The University of Nebraska-Lincoln is hiring a postdoc in commutative algebra, algebraic geometry, or related fields, funded by the NSF RTG Commutative Algebra at Nebraska. For more information, see the mathjobs post.

Ben Briggs is advertising a PhD position at Imperial College London, to start in October 2025 (there may be some flexibility in this). Please pass this announcement onto any students you know who might be a good fit!

The successful candidate will, very broadly, work on topics in commutative algebra and representation theory using homological/homotopical methods. Slightly less broadly, the plan is to produce a thesis on the structure of Hochschild cohomology and its relation to other things like the cotangent complex, support varieties, K-theory, proxy-small objects, Koszul duality, etc.

To apply, first write to Ben Briggs (b.briggs@imperial.ac.uk) with a description of your own background and interests, and the names of some reference writers. After that, if we decide your background fits well, you should formally apply through the “My Imperial” system here.


In your application you should say that you are interested in working with Ben Briggs, and you should discuss in detail your background and your interest in the potential project. If you write to him then you can discuss potential thesis ideas in more detail, and this could help your application a lot.

Please apply soon: a shortlist will be made in early November and hold some interviews shortly after that. At present the funding is for home fees, but international applicants will have a chance to apply for a top up that will hopefully cover the full tuition amount.

The Miller Postdoctoral Fellowship is a unique three-year fellowship that offers early career scientists an interdisciplinary research experience at UC Berkeley. Nominations are open until September 12, 2024. Nomination Instructions are at can be found at

This three-year position with no teaching requirement (PhD between January 2023 and August 2025) comes with mentorship and lots of social activity (weekly lunches, etc) in an interdisciplinary community. There are about 10 positions/year across all sciences, and requires naming a mentor in the Berkeley faculty.

There is a new occasional online seminar series “Macaulay2: under the hood”, exploring mathematical, algorithmic, and software issues behind the Macaulay2 software program.  The goal is for talks to be accessible to a range of backgrounds, and all are welcome. Fill out this form to sign up for the mailing list for this series.

The first talk will take place on zoom here, meeting code 972 6877 8504, with password Macaulay2. The first talk will be on

June 25, 2024 at 8:30 PDT, 10:30 CDT, 11:30 EDT, 16:30 BST, 17:30 CEST.

Here are the details for the first talk:

Speaker: Mike Stillman (Cornell) (M2 developer)

Abstract:

This is the first talk in the “M2: under the hood” series. The idea of this series is to understand Macaulay2 in more depth; in particular, understand how its computations work, in order to be able to more effectively use Macaulay2.

In this first talk, I will first describe the overall structure of the Macaulay2 system (the different parts: interpreter, engine, Core, packages, GitHub repository, git issues, and so on). After that, we will focus on one of the main computations in Macaulay2, computing free resolutions and minimal Betti numbers. We will provide an overview of the algorithm(s) used, the different ways one can call free resolutions, how they differ, and how Macaulay2 caches its results. We will also discuss how to speed up computations (if possible!) and how to deal with inhomogeneous and multi-graded input ideals or modules.

Obituary by Winfried Bruns and Aldo Conca

MSRI/SLMath held an event in Herzog’s memory on May 6, 2024, which was recorded.

Below are some testimonials on Herzog’s life and work:

“Beyond his impressive achievements, in the last two decades Jurgen kindly supported many young researchers from different countries by teaching them how to research and how to write papers. In this regard, he shared his fantastic ideas with young researchers and published joint papers. He acted like a scientific father to the young researchers. He supervised several Iranian Ph.D students himself, or, acted as a join advisor. At the same time, he taught them scientific ethics.We know many great Mathematicians but without any doubt he was exceptional in this regards.

We never forget his generosity and encouragement inspired countless individuals.” – Siamak Yassemi

“Jürgen was an exceptional mind, known for his incredible inventiveness and productivity, even in his final days. His contributions to mathematics will be deeply missed and remembered for years to come.

But beyond his impressive achievements, Jürgen was a kind and supportive mentor, particularly to Pakistani researchers. His generosity and encouragement inspired countless individuals, and his legacy will live on through the many lives he touched.” – Imran Anwar
