On the sharpness of a superconvergence estimate in connection with one-dimensional Galerkin methods

<p/> <p>The present paper studies some aspects of approximation theory in the context of one-dimensional Galerkin methods. The phenomenon of superconvergence at the knots is well-known. Indeed, for smooth solutions the rate of convergence at these points is <inline-formula><grap...
