A preconditioned Krylov subspace method for linear inverse problems with general-form Tikhonov regularization
Haibo Li
Tikhonov regularization is a widely used technique in solving inverse problems that can enforce prior properties on the desired solution. In this paper, we propose a Krylov subspac…

The joint bidiagonalization of a matrix pair with inaccurate inner iterations
Haibo Li
The joint bidiagonalization (JBD) process iteratively reduces a matrix pair to two bidiagonal forms simultaneously, which can be used for computing a partial generalized…
