A new Lagrange multiplier approach for constructing structure-preserving schemes, II. bound preserving
Qing Cheng, Jie Shen
In the second part of this series, we use the Lagrange multiplier approach proposed in the first part \cite{CheS21} to construct efficient and accurate bound and/or mass preserving…

A new Lagrange multiplier approach for constructing structure preserving schemes, I. positivity preserving
Qing Cheng, Jie Shen
We propose a new Lagrange multiplier approach to construct positivity preserving schemes for parabolic type equations. The new approach introduces a space-time Lagrange multiplier…

Modeling and simulation of nuclear architecture reorganization process using a phase field approach
Qing Cheng, Pourya Delafrouz, Jie Liang +2
We develop a special phase field/diffusive interface method to model the nuclear architecture reorganization process. In particular, we use a Lagrange multiplier approach in the ph…
