Abstract

We investigate the asymptotic behavior of nonautonomous discrete dynamical systems governed by the system of difference equations (recursive equations): yj(n+1)=Fj(n,y(n)); j=1,,k,n=0,1,2,, where y(n)=(y1(n),,yk(n))k, y(0)=x, and Fj(n,) is a mean of k (2) positive real numbers, that is, a real-valued function satisfying the internality property min(x)Fj(n,x)max(x).
