Constant solutions in second osOrder linear homogeneous difference equations with variable coefficientsJesús CarmeloAbderramán MarreroauthorThe constant solutions of second order linear and homogeneous difference equation with variable coefficients are analyzed. Thus, a sufficient condition for the existence of the constant solution, with any initial solution, is provided. Also, fixed points and invariant subsets of the solutions are considered. Finally, a necessary and sufficient condition to maintain the existence of non-trivial fixed points in the product of transfer matrices of two dimensions, is given.Mathematics2008Slovak University of Technology in BratislavaArticle
