Reflection group presentations arising from cluster algebras

Speaker: 
Robert Marsh (Leeds)
Date/Time: 
Mon, 30/01/2012 - 16:30
Room: 
M103
Seminar series: 

We give a presentation of a finite crystallographic reflection group
in terms of an arbitrary seed in the corresponding cluster algebra of
finite type and interpret the presentation in terms of companion bases in
the associated root system. The talk will include an introduction to
cluster algebras.

Joint work with Michael Barot (UNAM, Mexico).
