In this paper, we consider an algorithm that allows you to calculate the sequence of the main minors of the Toeplitz band matrix associated with the Cauchy problem for a two-dimensional polynomial difference operator with constant coe cients, with an upper (lower) band width equal to one, which allows us to determine the non-degeneracy of such a matrix and, therefore, draw conclusions on the solvability of the Cauchy problem
Keywords:
polynomial difference operator, Cauchy problem, solvability, band matrix, toeplitz matrix, main minor.
