Orban D., Arioli M. Iterative Solution of Symmetric Quasi-Definite Linear Systems

SIAM, 2017. — 101 p. — ISBN 9781611974720.Решения Симметрических Квазиопределенных Линейных СистемNumerous applications, including computational optimization and fluid dynamics, give rise to block linear systems of equations said to have the quasi-definite structure. In practical situations, the size or density of those systems can preclude a factorization approach, leaving only iterative methods as the solution technique. Known iterative methods, however, are not specifically designed to take advantage of the Read more...Preliminaries
