A nonlinear stochastic differential equation with the order of nonlinearity
higher than one, with several discrete and distributed delays and time varying
coefficients is considered. It is shown that the sufficient conditions for
exponential mean square stability of the linear part of the considered
nonlinear equation also are sufficient conditions for stability in probability
of the initial nonlinear equation. Some new sufficient condition of stability
in probability for the zero solution of the considered nonlinear non-autonomous
stochastic differential equation is obtained which can be considered as a
multi-condition of stability because it allows to get for one considered
equation at once several different complementary of each other sufficient
stability conditions. The obtained results are illustrated with numerical
simulations and figures.Comment: Published at https://doi.org/10.15559/18-VMSTA110 in the Modern
