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
