        "abstract": "Sufficient stability criteria for classes of parametrically excited differential equations  are developed and applied to example problems of a dynamical nature.\n     Stability requirements are presented in terms of 1) the modulus of the amplitude of the  parametric terms, 2) the modulus of the integral of the parametric terms and 3) the modulus of the  derivative of the parametric terms.\n     The methods employed to show stability are Liapunov's Direct Method and the Gronwall Lemma.  The type of stability is generally referred to as asymptotic stability in the sense of Liapunov.\n     The results indicate that if the equation of the system with the parametric terms set equal  to zero exhibits stability and possesses bounded operators, then the system will be stable under  sufficiently small modulus of the parametric terms or sufficiently small modulus of the integral of the  parametric terms (high frequency). on the other hand if the equation of the system exhibits individual  stability for all values that the parameter assumes in the time interval, then the actual system will be  stable under sufficiently small modulus of the derivative of the parametric terms (slowly varying).",
