In the second part of this series, we use the Lagrange multiplier approach proposed in the first part [7] to construct efficient and accurate bound and/or mass preserving schemes for a class of semi-linear and quasi-linear parabolic equations. We establish stability results under a general setting, and carry out an error analysis for a secondorder bound preserving scheme with a hybrid spectral discretization in space. We apply our approach to several typical PDEs which preserve bound and/or… Expand

Maximum-Principle-Satisfying Third Order Discontinuous Galerkin Schemes for Fokker-Planck Equations
It is shown that a modified limiter can preserve the strict maximum principle for DG schemes solving Fokker--Planck equations, and a scaling limiter for the DG method with first order Euler forward time discretization is proposed to solve the one-dimensional Fokkersonian equations. Expand
Stability and Convergence Analysis of Fully Discrete Fourier Collocation Spectral Method for 3-D Viscous Burgers’ Equation
The main result in this work is that the pseudospectral method coupled with the carefully designed time-discretizations is stable provided only that the time-step and spatial grid-size are bounded by two constants over a finite time. Expand
