March 4th - Leonid Positselski (IM CAS):
COUNTABLY GENERATED ENDO-SIGMA-COPERFECT MODULES
Abstract: A question of Angeleri Hugel and Saorin about perfect
decompositions of endo-Sigma-coperfect modules can be formulated as
follows: if a module M is Sigma-coperfect over its endomorphism
ring, does it follow that every local direct summand in M is a direct
summand? In this talk I will prove that if M is a countably generated
endo-Sigma-coperfect module, then every countably indexed local direct
summand in M is a direct summand. The argument using Bass flat
contramodules over topological rings with a countable base of
neighborhoods of zero belongs to Jan Stovicek and the speaker.

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