We introduce a novel numerical method for solving two-sided space fractional partial differential equations in two-dimensional case.The approximation of the spa
The adaptive simpler block GMRES method was investigated by Zhong et al.(J Comput Appl Math 282:139-156, 2015) where the condition number of the adaptively chos
In this paper,we design an efficient domain decomposition(DD)preconditioner for the saddle-point problem resulting from the mixed finite-element discretization
We present an iterative algorithm for approximating an unknown function sequentially using random samples of the function values and gradients. This is an exten
