Convergence analysis of TriCG and TriMR for symmetric quasi-definite linear systems
Kui Du, Jia-Jun Fan
TriCG and TriMR are two short-recurrence iterative methods introduced by Montoison and Orban [SIAM J.\ Sci.\ Comput., 43 (2021), pp.\ A2502--A2525] for solving symmetric quasi-defi…

TriCG with deflated restarting for symmetric quasi-definite linear systems
Kui Du, Jia-Jun Fan
TriCG is a short-recurrence iterative method recently introduced by Montoison and Orban [SIAM J. Sci. Comput., 43 (2021), pp. A2502--A2525] for solving symmetric quasi-definite (SQ…
