Global behavior of two-dimensional difference equations system with two period coefficients
(Tbilisi Center for Mathematical Sciences, 2020)
In this paper, we investigate the following system of difference equations x(n+1) = alpha(n)/1 + y(n)x(n-1), y(n+1) = beta(n)/1 + x(n)y(n-1), n is an element of N-0, where the sequences (alpha(n))(n is an element of ...
