Abstract: | Let W be the Weyl group of type F 4: We explicitly describe a finite set of basic braid I *-transformations and show that any two reduced I *-expressions for a given involution in W can be transformed into each other through a series of basic braid I *-transformations. Our main result extends the earlier work on the Weyl groups of classical types (i.e., A n , B n , and D n ). |
