Asynchronous iterative algorithms have emerged as a robust alternative to traditional synchronous methods for solving large-scale linear systems.

This paper considers two latest randomized iterative methods for solving large-scale linear systems and linear least-squares problems|greedy randomized Kaczmarz (GRK) method and greedy randomized ...

The concept of the field of value to localize the spectrum of the iteration matrices of the skew-symmetric iterative methods is further exploited. Obtained formulas are derived to relate the fields of ...
