Functional Models for Commuting Hilbert-Space Contractions,traction. We identify additional invariants . in addition to the Sz.-Nagy–Foias characteristic function Θ. for the product operator . so that the combined triple . becomes a complete unitary invariant for the original operator tuple .. For the case . ≥ 3 in general there is no commutative isometric

The Extended Aluthge Transform,ator such that . . = ., we define the . Aluthge transform of . associated with . by .. First, we establish some basic properties of Δ.; second, we study the fixed points of the extended Aluthge transform; third, we consider the case when . is an idempotent; next, we discuss whether Δ. leaves invaria

Invariance of the Essential Spectra of Operator Pencils,fficients of two pencils are derived which guarantee the same essential spectrum. This is done by exploiting a strong relation between an operator pencil and a specific linear subspace (linear relation).

,A Survey on Classification of C∗-Algebras with the Ideal Property,s have the ideal property. We will review some results on classification of C.-algebras including real rank zero C.-algebras and unital, simple C.-algebras. Then we will present some invariants and discuss the relations between them. Our goal is to try to give a picture of current research about cla

A Survey on the Arveson-Douglas Conjecture,omial rings. It originated from multi-variable operator theory but turns out to have various connections outside this field. In this survey, we will introduce the conjecture, describe its backgrounds, applications, and recent developments. Several related questions are also included in this survey.
