SUMMARY:Math Seminar Series
DESCRIPTION:
Combinatorics and Graph Theory\n
\n
Samantha Dahlberg
from Arizona State University will be speaking.\n
\n
The
seminar is titled "Diameters
of Graphs of Reduced Words of Permutations."\n
\n
This
seminar will take place online via Zoom.\n
\n
Abstract:\n
It
is a classical result that
any two reduced words of a permutation in
the symmetric group can be transformed into one
another by a sequence of long braid moves
and commutation moves. In this talk we will discuss
the diameters of these connected graphs
formed from the reduced words connected by
single moves. Recently, the diameter has been
calculated for the longest permutation n...21
by Reiner and Roichman as well as Assaf. In
this talk we present our results on diameters
for certain classes or permutation . We also
make progress on conjectured bounds of the
diameter by Reiner and Roichman, which are based
on the underlying hyperplane arrangement.\n\n
