                             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. Lukus (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.

Dear Colleagues,

     Many of you may recall that a year ago in Prague, during the
latest meeting in the series of Algebra Conferences organized by the
algebraists of Budapest, Chemnitz, Prague and Torun, it was decided
that the next conference be held in Budapest in the year
2001. It is our pleasure to announce now that the

        5th Budapest--Chemnitz--Prague--Torun Algebra Symposium

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.

     The lectures will be held in the main lecture hall of the Alfred
Renyi Mathematical Institute of the 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.

     We plan to have 9 invited lectures and the rest of the time should be
devoted to contributed talks (20-25 minutes each). Here is the list of main
speakers:

           H. Andersen     (Aarhus, Denmark)
           V. Drensky      (Sofia, Bulgaria)
           D. Happel       (Chemnitz, Germany)
           S. Koenig       (Leicester, United Kingdom)

     To keep the costs at a minimum level, we shall make efforts to secure
affordable accommodation for the participants and we also plan to have
organized lunches. It is, however, almost certain that we will have no funds
