Hybrid BSQI-WENO Based Numerical Scheme for Hyperbolic Conservation Laws
Rakesh Kumar, S. Baskar
In this paper, we intend to use a B-spline quasi-interpolation (BSQI) technique to develop higher order hybrid schemes for conservation laws. As a first step, we develop cubic and…

Quasilinear viscous approximations to scalar conservation laws
Ramesh Mondal, S. Sivaji Ganesh, S. Baskar
We prove the convergence of quasilinear parabolic viscous approximations to the entropy solution (in the sense of Bardos-Leroux-Nedelec) of a scalar conservation law, considered on…
