On quasi-similarity and putnam-fuglede property of operators in Hilbert spaces
(University of Nairobi, 2014)
The problem of finding conditions under which two given operators say A and B have equal spectra has been
considered by several authors. In this paper we show that quasi-similar operators 𝐴 and 𝐵 which satisfy the
Putnam- ...
