Title: Braid Group Action on the Refolded Tilting Complexes of the Brauer 
Star Algebra 

Authors:  Mary Schaps and  Evelyne Zakay-Illouz.

Abstract:  In an earlier paper we showed that the set of "two-restricted" 
tilting complexes for the Brauer star algebra is in one-to-one correspondence 
with the set of brauer trees with an additional structure called a pointing, 
which determines the folding of the complex.  Here we show that the subgroup 
of self-equivalences of the Brauer star algebra obtained by going out with 
one pointing and returning by another is generated by e generators which 
satisfy the braid relations for the Euclidean diagram which is a cycle.
