Abstract: In this paper a result on distribution of the eigenvalues of real entry irreducible matrix whose module are equal to the spectral radius is presented, which is applied to give very simple proof for a theorem in ref.[2].Then a sufficient and necessary condition on the stability and asymptotical stability of linear discrete dynamical systems is given.

Key words: linear discrete time dynamical systems, stability, the spectral radius, asymptotical stability
