Using a recently proved equivalence between disconjugacy of the 2nth-order difference equation tt v--'--O and solvability of the correeponding Riccati matrix difference equation, it is shown that the equation L(I/) = 0 is di~onjugate on a given interval if and only if the operator L admits the facto
