I shall list a number of problems that I have
come across recently involving Coxeter groups,
root systems, Kac-Moody algebras,
and associated groups. The basic idea of
many of them will be how to encapsulate
an infinite structure in a small amount of data.
The prototype is the result of Brink and Howlett on
the automaticity of Coxeter groups.
See the web abstract for some illustrations.
After the seminar we will take the speaker to lunch.
See the Algebra Seminar web page for information about other seminars in the series.
