The workshop “FACARD, Frobenius Action in Commutative Algebra: Recent Developments” will be held at the Institute of Mathematics of the University of Barcelona on January 16 – 18, 2019.

The focus of the workshop is on recent developments in positive characteristic algebra and other related topics. It is addressed to Ph.D. students, postdocs and interested researchers in general. There will be two minicourses at graduate level and research talks given by international experts and young emerging scientists.

Minicourse speakers:

- Holger Brenner (Universität Osnabrück)
- Linquan Ma (Purdue University)

Speakers:

- Josep Àlvarez Montaner (Universitat Politècnica de Catalunya)
- Angélica Benito (Universitad Autonoma de Madrid)
- Javier Carvajal Rojas (University of Utah)
- Alberto F. Boix (Ben-Gurion University of the Negev)
- Ricardo García López (Universitat de Barcelona)
- Eloísa Grifo (University of Michigan)
- Jack Jeffries (University of Michigan)
- Jonathan Montaño (New Mexico State University)
- Julio José Moyano Fernández (Universitat Jaume I de Castelló)

Jean-Louis Koszul, whose name is familiar to commutative algebraists as the namesake of the Koszul complex, passed away on 12 January 2018. Koszul was a student of Henri Cartan, one of the creators of the CIRM, and a member of Bourbaki. Altogether a giant of 20th century mathematics.

We are deeply sad to tell the community that Jan-Erik Roos passed away December 15, 2017.

His colleagues in Stockholm sent the following:

Jan-Erik Roos studies in Paris resulted in a substantial work on Noetherian categories. Since 1970 he held a professorship in Stockholm. One of his greatest achievements was to bring together two fields of mathematics, algebraic topology and commutative algebra. He noted that there were analogous results in these fields, and a fruitful cooperation began as a result. He had many research students taking part in this work. Jan-Erik was successful in using computers to solve problems and finding counterexamples. He was very active to the very last.

We are deeply sad to tell the community of the passing of Ragnar-Olaf Buchweitz, in Toronto on November 11 2017.

Ragnar made deep and influential contributions to an incredible range of topics, including singularity theory, deformations, commutative and noncommutative algebra, representation theory, and algebraic geometry. He was a generous mentor and advisor of graduate students, and a particular friend to the people behind this website. His passing is a great loss to our community.

We are sorry to write that Liam O’Carroll, born June 10, 1945, and known in the international community of commutative algebraists for his work on various aspects of the subject but especially on uniform Artin–Rees Theorems, died on 25 October 2017, of myeloma and acute myeloid leukemia. In accordance with his wishes, his body was donated for medical research. Messages of condolence can be sent to liamocarrollmemories@yahoo.com.

Our thoughts are with his family and friends.

Obituary Notice.

We added information about Craig Huneke’s talk in the “Current Events Bulletin” session at the San Diego JMM to our post about the JMM. See there for details.

We are deeply sad to share with the commalg community that Uwe Storch has passed away on September 17, 2017. Uwe was known for his work in commutative algebra and algebraic/analytic geometry.

Our thoughts are with his friends and family.

In recognition of the excitement of the July 2017 workshop “The Prospects for Commutative Algebra” (http://commalg2017.jp), the journal Acta Mathematical Vietnamica (https://link.springer.com/journal/40306) has agreed to have a special issue devoted to commutative algebra, to be published in January 2019. We —

- Dale Cutkosky
- David Eisenbud
- Shiro Goto
- Jürgen Herzog
- Takayuki Hibi
- Ngô Việt Trung

— will serve as the editorial committee for the issue. We hope to make it an important document showing some of the best current research in the field, and we invite submissions.

Feel free to write to us with any questions. The deadline for final versions of the papers is September 2018, so we must ask for submissions by March 2018 at the latest.

Best regards,

Dale, David, Jürgen, Shiro, Takayuki, Trung

The 2017 Mathematical Society of Japan Algebra Prize has been awarded to Toshiyuki Katsura for work in algebraic geometry in positive characteristic, and Mitsuyasu Hashimoto for his work in invariant theory and its applications to commutative ring theory. Congratulations! The third recipient of this year’s prize is Masanobu Kaneko.

There is one new Postdoctoral Position at the Osnabrück University offered by the DFG-Research Training Group “Combinatorial Structures in Geometry” and in particular, researchers from commutative algebra are invited to apply.

The deadline is April 07, 2017.

Here are two fantastic pieces of news, with one piece of bad news in the middle.

The 2016 Mathematical Society of Japan Algebra Prize has been awarded to Kazuhiko Kurano (Meiji University), for his work in intersection theory over local rings and its application to the theory of Cohen-Macaulay modules. Congratulations! The other recipients of this year’s prize are Hidenori Katsurada and Masa-hiko Saito.

The Mathematical Sciences Program of the National Security Agency has announced that they will not be able to fund any new projects in fiscal year 2017.

Yves André has proved the direct summand conjecture using

perfectoid methods and Bhargav Bhatt has simplified the proof greatly and

also proved the derived version. Here are André’s preprint and Bhatt’s preprint.
