A New Multi-dimensional Relaxation Scheme for Nonlinear Hyperbolic Conservation Laws Based on Bicharacteristics. - Bangalore: Department of Mathematics, Indian Institute of Science: 2008 - A new genuinely multi-dimensional relaxation scheme is proposed. Based on a new discrete velocity Boltzmann equation, which is an improvement over previously introduced relaxation systems in terms of isotropic coverage of the multidimensional domain by th
