DESCRIPTION:Abstract: m-Isometries are Hilbert space linear operators satis
fying an operator equation that generalizes the notion of isometries. Thes
e operators were introduced and studied by Agler. In the late nineties, A
gler, Helton and Stankus showed that any m-isometry on a finite dimension
al Hilbert space can be decomposed as a sum of an isometry and a commuting
nilpotent operator. The converse of this and other algebraic properties o
f m-isometries have been proved in recent years. I will discuss how the he
reditary functional calculus can be used to provide simplified proofs of t
hese as well as more general results, even in the setting of commuting tu
ples of operators.\n\nHost: Christopher Felder\n\nView Presentation
