Solvability of a general class of two-dimensional hyperbolic-cotangent-type systems of difference equations
Abstract We show that the following class of two-dimensional hyperbolic-cotangent-type systems of difference equations xn+1=un−kvn−l+aun−k+vn−l,yn+1=wn−ksn−l+awn−k+sn−l,n∈N0, $$ x_{n+1}=\frac{u_{n-k}v_{n-l}+a}{u_{n-k}+v_{n-l}},\quad \quad y_{n+1}= \frac{w _{n-k}s_{n-l}+a}{w_{n-k}+s_{n-l}},\quad n\in...
