Variations on Hermite methods for wave propagation
Arturo Vargas, Jesse Chan, Thomas Hagstrom +1
Hermite methods, as introduced by Goodrich et al., combine Hermite interpolation and staggered (dual) grids to produce stable high order accurate schemes for the solution of hyperb…

On the stability of time-domain integral equations for acoustic wave propagation
Charles L. Epstein, Leslie Greengard, Thomas Hagstrom
We give a principled approach for the selection of a boundary integral, retarded potential representation for the solution of scattering problems for the wave equation in an exteri…
