Abstract: A collocation-Galerkin scheme is proposed for an initial-boundary value problem for a first order hyperbolic equation in one space dimension. The Galerkin equations satisfied by the approximating solution are obtained from a weak-weak formulation of the initial-boundary value problem. The collocation points are taken to be affine images of the roots of the Jacobian polynomials of degree $ r - 1$ on [0, 1] with respect to the weight function $ x(1 - x)$. Optimal $ {L^\infty }({L^2})$-norm estimates of the error are derived.
