Jan Šaroch (MFF UK): Consistency of failure of the Enochs Conjecture (à la AI&Zhang)

Abstract: Following the preprint arXiv:2609.25495v1, we will show that in any extension of ZFC without measurable cardinals, there exists a K-algebra R and a class of right R-modules C such that C is covering in Mod-R, but C is not closed under countable direct limits.

Previous program:

The Algebra Seminar was founded by Vladimir Korinek in the early 1950's and continued by Karel Drbohlav until 1981. The seminar resumed its activities in 1990 under the guidance of Jaroslav Jezek and Tomas Kepka. Since 1994, the seminar is headed by Jan Trlifaj.

Presently, the seminar is supported by GACR. It serves primarily as a platform for presentation of recent research of the visitors to the Department of Algebra as well as members of the Department and their students.
