【Abstract】 In this paper, we generalized the Важевскийs estimate for the solution of the time varying linear system of differential equations and obtained the more precise estimate for the spectrum of the time varying system. These results may be applied to the discussion for the stability of a class of time varying nonlinear systems.更多还原
