SUMMARY:Shuo Li (Université du Québec à Montréal): On the number of squ
 ares in a finite word
DESCRIPTION:Shuo Li: A conjecture of Fraenkel and Simpson states that the n
 umber of distinct squares in a finite word w is bounded by its length. In 
 this talk\, we will review this conjecture from the perspective of the top
 ological proprieties of the Rauzy graphs of w. We prove this conjecture by
  giving a stronger statement: the number of distinct squares in a finite w
 ord w is bounded by the length of w minus the number of distinct letters i
 n w.\nVideo and slides here : https://www.i2m.univ-amu.fr/wiki/Combinatori
