“…The latter has been recently derived in a unified approach to generalized harmonic oscillators (see, for example, [27], [29], [98], [105], [153] and the references therein). These solutions can be verified by a direct substitution with the aid of Mathematica computer algebra system [91] (see also [92]), [105], and [106]. (In retrospect, the simplest special case β 0 = ±1 and α 0 = γ 0 = δ 0 = ε 0 = κ 0 = 0 is the ground oscillator state [55], [64], [96], [119], [143], [144].…”
