5th BUDAPEST--CHEMNITZ--PRAHA--TORUN
CONFERENCE IN ALGEBRA

Budapest, Hungary, June 14-16, 2001.

Second announcement

As it was announced a few months ago (in the last century!), the

5th Budapest--Chemnitz--Prague--Torun Conference in Algebra

will take place in Budapest from June 14 (Thursday) to June 16 (Saturday), 2001, with June 13 and June 17 as suggested arrival and departure days.

Scientific program.

The lectures will be held in the main lecture hall of the Alfréd Rényi Mathematical Institute, Hungarian Academy of Sciences. The main topic of the conference will be representation theory of algebras with an outlook to related areas (group rings, Lie algebras, algebraic geometry, general ring theory etc.), however, any other algebraic topic is welcome for short talks.

Here is the list of the invited (one hour) lectures:

H. Andersen (Aarhus, Denmark): Twisted Verma modules

V. Drensky (Sofia, Bulgaria): Asymptotic behaviour of polynomial identities of matrices

D. Happel (Chemnitz, Germany): Hereditary categories with tilting object over arbitrary base fields

S. König (Leicester, United Kingdom): Repeating patterns in decomposition matrices of general linear groups

E. Lukács (Budapest, Hungary): Quasi-hereditary extension algebras

C.M. Ringel (Bielefeld, Germany): Subgroups of finite abelian groups

D. Simson (Torun, Poland): On representation theory of coalgebras

A. Smoktunowicz (Warsaw, Poland): On results connected to the Köthe conjecture

J. Trlifaj (Prague, Czech Republic): Approximations of modules

Sessions of short talks (25 minutes) will also be organized. Participants are welcome to contribute. At present we do not plan to have parallel sessions. The lectures will start on Thursday, June 14 at 9 a.m. The expected closing of the conference is on Saturday afternoon, June 16.

Accommodation.

Since hotel prices tend to be rather high in Budapest (one single or double room in the downtown area could cost 150 DM/night and up), we tried to search for affordable accommodation for the participants. However, due to the fact that the spring term at universities finishes only at the beginning of July, and also some reconstruction is planned in our traditional guest houses, cheap accommodation which would still be priced at a reasonable level, is rather limited. Thus we encourage everyone to make a reservation as soon as possible either through us (preferably by the end of March) or on her/his own. Please, let us know of any special needs concerning acommodation (travelling with a family, staying longer etc.). We shall make all efforts to find suitable accommodation for everyone.
