On solution of differential-algebraic equations by collocation-variation splines

L. Solovarova and M. Bulatov

Numerical methods for solving initial value problems for differential-algebraic equations are proposed. The approximate solution is represented as a continuous vector spline whose coefficients are found using the collocation conditions stated for a subgrid with the number of collocation points less than the degree of the spline and the minimality condition for the norm of this spline in the corresponding spaces. Numerical results for some model problems are presented. The work was supported RFBR Grants 11-01-00639-a and 13-01-93002 Viet-a.
