Fully discrete energy-dissipative and conservative discrete gradient particle methods for a class of continuity equations
Jingwei Hu, Samuel Q. Van Fleet, Andy T. S. Wan
Structure-preserving particle methods have recently been proposed for a class of nonlinear continuity equations, including aggregation-diffusion equation in [J. Carrillo, K. Craig,…
Minimal Norm Discrete Multiplier Method
Erick Schulz, Andy T. S. Wan
We introduce an extension to the Discrete Multiplier Method (DMM), called Minimal Norm Discrete Multiplier Method (MN-DMM), where conservative finite difference schemes fo…
Improving sampling efficacy on high dimensional distributions with thin high density regions using Conservative Hamiltonian Monte Carlo
Geoffrey McGregor, Andy T. S. Wan
Hamiltonian Monte Carlo is a prominent Markov Chain Monte Carlo algorithm, which employs symplectic integrators to sample from high dimensional target distributions in many applica…
Conservative Integrators for Vortex Blob Methods
Cem Gormezano, Jean-Christophe Nave, Andy T. S. Wan
Conservative symmetric second-order one-step integrators are derived using the Discrete Multiplier Method for a family of vortex-blob models approximating the incompressible Euler'…
Conservative Integrators for Many-body Problems
Andy T. S. Wan, Alexander Bihlo, Jean-Christophe Nave
Conservative symmetric second-order one-step schemes are derived for dynamical systems describing various many-body systems using the Discrete Multiplier Method. This includes cons…
Conservative Integrators for Piecewise Smooth Systems with Transversal Dynamics
Anil N. Hirani, Andy T. S. Wan, Nikolas Wojtalewicz
We introduce conservative integrators for long term integration of piecewise smooth systems with transversal dynamics and piecewise smooth conserved quantities. In essence, for a p…
