Indefinite Ruhe’s Variant of the Block Lanczos Method for Solving the Systems of Linear Equations
In this paper, we equip Cn with an indefinite scalar product with a specific Hermitian matrix, and our aim is to develop some block Krylov methods to indefinite mode. In fact, by considering the block Arnoldi, block FOM, and block Lanczos methods, we design the indefinite structures of these block K...
