Inner iterations in the shift-invert residual Arnoldi method and the Jacobi-Davidson method
《Science China Mathematics》2014年第8期1733-1752,共20页JIA ZhongXiao LI Cen 
supported by National Basic Research Program of China(Grant No.2011CB302400);National Natural Science Foundation of China(Grant No.11071140)
We establish a general convergence theory of the Shift-Invert Residual Arnoldi(SIRA)method for computing a simple eigenvalue nearest to a given targetσand the associated eigenvector.In SIRA,a subspace expansion vecto...

On convergence of the inexact Rayleigh quotient iteration with the Lanczos method used for solving linear systems被引量:2
《Science China Mathematics》2013年第10期2145-2160,共16页JIA ZhongXiao 
supported by National Basic Research Program of China(Grant No.2011CB302400);National Natural Science Foundation of China(Grant No.11071140)
For the Hermitian inexact Rayleigh quotient iteration (RQI), we consider the local convergence of the inexact RQI with the Lanczos method for the linear systems involved. Some attractive properties are derived for t...
