On perturbation of Drazin invertible linear relations
UDC 517.98 We study the stability of regular, finite ascent, and finite descent linear relations defined in Banach spaces under commuting nilpotent operator perturbations.  As an application, we give the invariance theorem of Drazin invertible spectrum under these perturbat...
