摘要
We consider the initial value problem for linear systems of second-order ordinarydifferential equations with an identically singular matrix multiplying the principal part. Sufficientconditions for the existence of a unique solution are given in terms of matrix polynomials. Forsuch problems, multistep difference schemes are proposed. An analysis of their stability andcalculations of a model example are carried out.
