Abstract

In this paper we generalize a strategy recently proposed by the author concerningintertwining operators. In particular, we discuss the possibility of extending ourprevious results in such a way to construct ͑almost͒ isospectral self-adjoint opera-tors living in different Hilbert spaces. Many examples are discussed in details.Many of them arise from the theory of frames in Hilbert spaces, others from theso-called g-frames.
