Abstract:

New methods are proposed for the numerical solution of systems of first-order differential equations. On each subinterval of a given mesh of size h, a polynomial of degree l is constructed, its parameters being determined by a multiple collocation technique. The resulting piecewise polynomial approximation is of order $O({h^{l + 1}})$ at the mesh points and between them. In addition, the jth derivatives of the approximation on each subinterval provide approximations of order $O({h^{l + 1 - j}})$, $j = 1, \ldots ,l$. Some of the methods proposed are shown to be A-stable or even strongly A-stable.
