An Invariant for Certain Operator Algebras
It is shown that the so-called principal function invariant, which is associated in a unitarily invariant way to operators with trace class self commutator TT(*) - T(*)T, is invariant under trace class perturbations of T and is an extension of the index of T-z to the whole plane. The connection of t...
