A high-order, conservative integrator with local time-stepping
William Throwe, Saul A. Teukolsky
We present a family of multistep integrators based on the Adams-Bashforth methods. These schemes can be constructed for arbitrary convergence order with arbitrary step size variati…

Short note on the mass matrix for Gauss-Lobatto grid points
Saul A. Teukolsky
The mass matrix for Gauss-Lobatto grid points is usually approximated by Gauss-Lobatto quadrature because this leads to a diagonal matrix that is easy to invert. The exact mass mat…
