Spectrum of Class wF(p,r,q) Operators
This paper discusses some spectral properties of class wF(p,r,q) operators for p>0, r>0, p+r≤1, and q≥1. It is shown that if T is a class wF(p,r,q) operator, then the Riesz idempotent Eλ of T with respect to each nonzero isolated point spectrum λ is selfadjoint and Eλℋ=...
