An augmented Lagrangian-based preconditioning technique for a class of block three-by-three linear systems
Fatemeh P. A. Beik, Michele Benzi
We propose an augmented Lagrangian-based preconditioner to accelerate the convergence of Krylov subspace methods applied to linear systems of equations with a block three-by-three…

On the tubular eigenvalues of third-order tensors
Fatemeh P. A. Beik, Yousef Saad
This paper introduces the notion of tubular eigenvalues of third-order tensors with respect to T-products of tensors and analyzes their properties. A focus of the paper is to discu…

Accelerating iterative solvers via a two-dimensional minimum residual technique
Fatemeh P. A. Beik, Michele Benzi, Mehdi Najafi-Kalyani
This paper deals with speeding up the convergence of a class of two-step iterative methods for solving linear systems of equations. To implement the acceleration technique, the res…
