... procedures are used for the approximation of the Da (0) with domains having a simpler shape For example, in the case of [4, Theorem 4.20, page 170] the domain which approximates the Da (0) is defined ... k =0 The Lyapunov function V can be found theoretically using relation (1.5) In the followings, we will shortly present the procedure of determination and approximation of the domain of attraction ... [3] E Kaslik, A M Balint, A Grigis, and St Balint, An extension of the characterization of the domain of attraction of an asymptotically stable fixed point in the case of a nonlinear discrete dynamical...
