Abstract
Asymptotic expansion series for the moment Lyapunov exponent and stabi lity index are constructed and justified for the two-dimensional linea r stochastic system close to a harmonic oscillator. As an example, a o ne-degree-of-freedom mechanical system parametrically excited in stiff ness and damping is considered and several terms of the expansion are obtained.
