(Regular) pseudo-bosons versus bosons [PDF]
Fabio BagarelloWe discuss in which sense the so-called {\em regular pseudo-bosons}, recently introduced by Trifonov and analyzed in some details by the author, are related to ordinary bosons. We repeat the same analysis also for {\em pseudo-bosons}, and we analyze the role played by certain intertwining operators, which may be bounded or not.View original: http://arxiv.org/abs/1207.2013
