Abstract:
By the direct Lyapunov method we prove a sufficient condition for the exponential dichotomy with weakened (in comparison with a case of arbitrary coefficients) requirements to the difference derivative of the Lyapunov function along the system trajectory. We give an illustrating example.
Keywords:
exponential dichotomy, indefinite Hermitian form, shell of an almost periodical matrix.
