摘要
A discrete dynamical system generated by a diffeomorphism f on a compact manifold is considered. The Morse spectrum is the limit set of Lyapunov exponents of periodic pseudotra-jectories. It is proved that the Morse spectrum coincides with the set of averagings of the function phi(x, e) - ln |Df(x)e| over the invariant measures of the mapping induced by the differential Df on the projective bundle.
