On quasisimilarity of polynomially bounded operators
Let T and R be absolutely continuous polynomially bounded operators, that is, P°°-calculus is well-defined for them, and let X and Y be quasiaffinities which intertwine T and R: XT = RX, YR = TY. If there exists a function g g H°° such that XY = g(R), then cr(T) = <r(R) and cre(T) = oe(R). Also,...
