"Absolute continuity and wandering vectors in Free semigroup algebras"
We sketch Kennedy's proof of the existence of a wandering vector for
an analytic / type L free semigroup algebra, drawing connections with
absolute continuity. We then discuss a strengthening of this result,
also due to Kennedy, that unifies many notions in the theory of free
semigroup algebras, and allowed for a Wold decomposition of isometric
tuples into a direct sum of a unilateral shift, an absolute continuity
unitary and a singular unitary.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within our Office of Indigenous Relations.
