Optimized sparse approximate inverse smoothers for solving Laplacian linear systems
Yunhui He, Jun Liu, Xiang-Sheng Wang
In this paper we propose and analyze new efficient sparse approximate inverse (SPAI) smoothers for solving the two-dimensional (2D) and three-dimensional (3D) Laplacian linear syst…
A Direct Parallel-in-Time Quasi-Boundary Value Method for Inverse Space-Dependent Source Problems
Yi Jiang, Jun Liu, Xiang-Sheng Wang
Inverse source problems arise often in real-world applications, such as localizing unknown groundwater contaminant sources. Being different from Tikhonov regularization, the quasi-…
A PDE-ODE Coupled Spatio-Temporal Mathematical Model for Fire Blight During Bloom
Michael Pupulin, Xiang-Sheng Wang, Messoud A Efendiev +2
Fire blight is a bacterial plant disease that affects apple and pear trees. We present a mathematical model for its spread in an orchard during bloom. This is a PDE-ODE coupled sys…
