Non-linear discrete-time Lur'e-type systems are considered. Explicit stability conditions are suggested. They are formulated in terms of the determinants of characteristic polynomials. Moreover, an estimate for the region of attraction of the zero solution is derived.
Keywords: non-linear discrete-time systems; stability; region of attraction.
