    "abstract": "An explicit solution of the equation for the classical harmonic oscillator\nwith smooth switching of the frequency has been found . A detailed analysis of\na quantum harmonic oscillator with such frequency has been done on the base of\nthe method of linear invariants. It has been shown that such oscillator\npossesses cofluctuant states, different from widely studied Glauber\u0027s coherent\nand \"ideal\" squeezed states.",
