A method of finding an approximate solution of an ordinary differential equation L[y]=0 by determining coefficients in an expansion y(x) = y_{0}(x) + \sum_{l=0}^{q}\alpha_{l} y_{l}(x) so as to make L[y] vanish at prescribed points; the expansion with the coefficients thus found is the sought approximation.
A service allowing multiple customers to locate network, server, and storage gear and connect them to a variety of telecommunications and network service providers, at a minimum of cost and complexity.
