Unconditionally Convergent High-Order Energy-Stable Compact Scheme for Nonlinear Sobolev Equation Through Convex Splitting
A high-order compact modified Crank-Nicolson scheme is proposed for the nonlinear Sobolev equation, in which a convex energy splitting approach is employed to address key computational challenges. By decomposing the energy functional into two convex components, a spatially fourth-order and temporally second-order compa...
