    "abstract": "We discuss the extension of the Lewis and Riesenfeld method of solving the\ntime-dependent Schr\\\"odinger equation to cases where the invariant has\ncontinuous eigenvalues and apply it to the case of a generalized time-dependent\ninverted harmonic oscillator. As a special case, we consider a generalized\ninverted oscillator with constant frequency and exponentially increasing mass.",
