Two-Grid Domain Decomposition Methods for the Coupled Stokes-Darcy System
Yizhong Sun, Feng Shi, Haibiao Zheng +2
In this paper, we propose two novel Robin-type domain decomposition methods based on the two-grid techniques for the coupled Stokes-Darcy system. Our schemes firstly adopt the exis…
An efficient numerical method for condition number constrained covariance matrix approximation
Shaoxin Wang
In the high-dimensional data setting, the sample covariance matrix is singular. In order to get a numerically stable and positive definite modification of the sample covariance mat…
A Non-uniform Time-stepping Convex Splitting Scheme for the Time-fractional Cahn-Hilliard Equation
Jun Zhang, Jia Zhao, JinRong Wang
In this paper, a non-uniform time-stepping convex-splitting numerical algorithm for solving the widely used time-fractional Cahn-Hilliard equation is introduced. The proposed numer…
Efficient energy-preserving methods for charged-particle dynamics
Ting Li, Bin Wang
In this paper, energy-preserving methods are formulated and studied for solving charged-particle dynamics. We first formulate the scheme of energy-preserving methods and analyze it…
Symmetric and symplectic exponential integrators for nonlinear Hamiltonian systems
Yajun Wu, Bin Wang
This letter studies symmetric and symplectic exponential integrators when applied to numerically computing nonlinear Hamiltonian systems. We first establish the symmetry and symple…
Long-term analysis of exponential integrators for highly oscillatory conservative systems
Bin Wang, Jiyong Li, Yonglei Fang
In this paper, we investigate the long-time near-conservations of energy and kinetic energy by the widely used exponential integrators to highly oscillatory conservative systems. T…
