Some perturbation results through localized SVEP

2016

Some classical perturbation results on Fredholm theory are proved and extended by using the stability of the localized single-valued extension property under Riesz commuting perturbations. In the last part, we give some results concerning the stability of property (gR) and property (gb.

Property (w) under compact or Riesz perturbations

2010

Si studia la permanenza della proprietà (w), una variante del Teorema di Weyl, nel caso che un operatore sia perturbato da un operatore compatto oppure di Riesz
