Asymptotic equivalence of difference equations. (English) Zbl 0942.39001

By means of the contraction mapping principle, an asymptotic equivalence is studied between the solutions of a finite-dimensional linear difference equation \(y(n+1)=A(n)y(n)\) and its nonlinear perturbation \(x({n+1})=A(n)x(n)+F\bigl (n,x(n),Tx(n)\bigr)\). Under certain conditions on these equations, a homeomorphism is shown between the sets of bounded solutions of the above equations.
