Energy and quadratic invariants preserving methods for Hamiltonian systems with holonomic constraints

Lei Li, Dongling Wang

We introduce a new class of parametricization structure-preserving partitioned Runge-Kutta (-PRK) methods for Hamiltonian systems with holonomic constraints. When the scalar par…

Complete monotonicity-preserving numerical methods for time fractional ODEs

Lei Li, Dongling Wang

The time fractional ODEs are equivalent to convolutional Volterra integral equations with completely monotone kernels. We therefore introduce the concept of complete monotonicity-p…

Numerical reconstruction of the spatial component in the source term of a time-fractional diffusion equation

Daijun Jiang, Yikan Liu, Dongling Wang

In this article, we are concerned with the analysis on the numerical reconstruction of the spatial component in the source term of a time-fractional diffusion equation. This ill-po…
