Conference ''algebraic coding theory''
March 2 and March 3, 2005
In the tradition of the roughly every second year organized
conference ''Representation theory around the channel''
the conference in march will be focused on methods linked and dealing with
algebraic coding theory. There will be one-hour lectures during
two days meant to introduce the problems to a non-specialist
audience.
