This paves the way for fast O(N N) and spectrally accurate mixed implicit-explicit time-marching of sets of linear and nonlinear equations in unbounded geometries. ...
Even when these operators are not parity-preserving, we demonstrate how a mixed expansion in interleaved Chebyshev rational functions TB_n(y) and SB_n(y) preserves the sparsity of their discretization. ...
Ian This appendix documents a method to obtain discretized matrices for operators composed of superpositions of powers of cosines, sines, and derivatives. ...
