Fast time-stepping discontinuous Galerkin method for the subdiffusion equation
Hui Zhang, Fanhai Zeng, Xiaoyun Jiang +1
The nonlocality of the fractional operator causes numerical difficulties for long time computation of the time-fractional evolution equations. This paper develops a high-order fast…
Schwarz methods by domain truncation
Martin J. Gander, Hui Zhang
Schwarz methods use a decomposition of the computational domain into subdomains and need to put boundary conditions on the subdomain boundaries. In domain truncation one restricts…
Convergence analysis of a solver for the linear Poisson--Boltzmann model
Xuanyu Liu, Yvon Maday, Chaoyu Quan +1
This work investigates the convergence of a domain decomposition method for the Poisson-Boltzmann model that can be formulated as an interior-exterior transmission problem. To stud…
Sparse Sampling Kaczmarz-Motzkin Method with Linear Convergence
Ziyang Yuan, Hui Zhang, Hongxia Wang
The randomized sparse Kaczmarz method was recently proposed to recover sparse solutions of linear systems. In this work, we introduce a greedy variant of the randomized sparse Kacz…
