Convergence of some iterative methods for symmetric saddle point linear systems
Y Notay - SIAM Journal on Matrix Analysis and Applications, 2019 - SIAM
We consider the iterative solution of linear systems with a symmetric saddle point system
matrix. We address a family of solution techniques that exploit the knowledge of a …

Multigrid preconditioners for mixed finite element methods of the vector Laplacian
Due to the indefiniteness and poor spectral properties, the discretized linear algebraic
system of the vector Laplacian by mixed finite element methods is hard to solve. A block …
