One-Dimensional Galerkin Methods and Superconvergence at Interior Nodal Points
In the case of one-dimensional Galerkin methods the phenomenon of superconvergence at the knots has been known for years [5], [7]. In this paper, a minor kind of superconvergence at specific points inside the segments of the partition is discussed for two classes of Galerkin methods: the Ritz–Galerkin method for …
