Abstract:

The equivalence between semi-Lagrangian and Lagrange–Galerkin schemes has been proved by R. Ferretti [J. Comp. Math. 28 (2010), no. 4, 461–473], [Numerische Mathematik 124 (2012), no. 1, 31–56] for the case of centered Lagrange interpolation of odd degree $p\le 13$. We generalize this result to an arbitrary odd degree, for both the case of constant- and variable-coefficient equations. In addition, we prove that the same holds for spline interpolations.
