Rings and Modules Seminar Thirtieth Anniversary Year!

Last updated: 2025-03-25

The Rings and Modules Seminar was founded in September of 1995 by G. Krause and T. Kucera.
We meet weekly during the fall and winter academic terms and occasionally during the spring and summer.
We present original research, survey talks, and tutorials on topics of interest.
We are always happy to hear talks by visitors.

The seminar is open to discussion of all aspects of ring theory and module theory,
and any related topics, such as algebraic geometry, or algebraic combinatorics;
or even more distantly connected subject areas.

We have a summary of the history of the activities of the seminar from 1995 to date.

We regret to announce the passing of our friend and colleague Guenter Krause, August 29, 2015.
We regret to announce the passing of our friend and occasional contributor to this Seminar,
Dr Susan Roddy, of Brandon University, October 05, 2017.

In the future...
We hope to run a somewhat irregular schedule in May/June 2025, times and locations TBA. We are always happy to try to find a time for a summer visitor to speak, but we do not expect to have a regular schedule in July and August. There will be talks from our students, post-docs, and guests. Volunteers?
May ? Date TBD	T. G. Kucera, University of Manitoba Model theory of quotients of modules by union-definable submodules abstract TBA
