Numerical Gauss-Lobatto quadrature in DG and instability
A naive transition to the non-linear Burgers' equation, where numerical quadratures were used for the stiffness matrix, was unsuccessful so I did the numerical quadrature version for the linear advection … From that I would assume that the stiffness matrix should be evaluated exactly in case of the linear advection, but I am getting a different form. …
