Linear difference operators of the second order are considered. Each operator is assigned a matrix operator of the first order. The statement about simultaneous invertibility of such operators was proved. A sufficient condition about invertibility of difference operators is obtained.
Mots-clés : kernel, image
Keywords: difference operators, invertibility of operators.
