A refined CJ--SS--RR method with a reliable removal approach of spurious Ritz values for the Hermitian eigenvalue problem
Zhongxiao Jia, Tianhang Liu
Under the hypothesis that the deviations of the desired eigenvectors of the matrix from the underlying subspace tend to zero, the Ritz vectors may not converge and have poor or…

New Jacobi--Davidson type methods for the large SVD computations
Jinzhi Huang, Zhongxiao Jia
In a Jacobi--Davidson (JD) type method for singular value decomposition (SVD) problems, called JDSVD, a large symmetric and generally indefinite correction equation is solved itera…
