commalg.org is...

a website for the commutative algebra community. In addition to news items and job postings of interest to commutative algebraists, we list all the conferences we hear about that focus at least partially on commutative algebra, and sometimes some photos of them. We also maintain as complete a list of commutative algebraists as possible, and a huge list of links to websites of interest.

current news: Jan-Erik Roos, 1935-2017 January 11th, 2018 (no responses)

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.
