    "abstract": "The Calogero model with negative harmonic term is shown to be equivalent to\nthe set of negative harmonic oscillators. Two time-independent canonical\ntransformations relating both models are constructed: one based on the recent\nresults concerning quantum Calogero model and one obtained from dynamical\n$sL(2,\\rr)$ algebra. The two-particle case is discussed in some detail.",
