On ampliation quasiaffine transforms of operators

Research output: Contribution to journalArticlepeer-review


In this paper, we study various connections of local spectral properties, invariant subspaces, and spectra when an operator S in L(H) is an ampliation quasiaffine transform of an operator T in L(H).
