On circulant and skew-circulant splitting algorithms for (continuous) Sylvester equations
Zhongyun Liu, Fang Zhang, Carla Ferreira +1
We present a circulant and skew-circulant splitting (CSCS) iterative method for solving large sparse continuous Sylvester equations , where the coefficient matrices $A…
The eigenstructures of real (skew) circulant matrices with some applications
Zhongyun Liu, Siheng Chen, Weijin Xu +1
The circulant matrices and skew-circulant matrices are two special classes of Toeplitz matrices and play vital roles in the computation of Toeplitz matrices. In this paper, we focu…
Characterizations and representations of core and dual core inverses
Jianlong Chen, Huihui Zhu, Pedro Patricio +1
In this paper, double commutativity and the reverse order law for the core inverse are considered. Then, new characterizations of the Moore-Penrose inverse of a regular element are…
The inverse along a product and its applications
Huihui Zhu, Pedro Patricio, Jianlong Chen
In this paper, we study the recently defined notion of the inverse along an element. An existence criterion for the inverse along a product is given in a ring. As applications, we…
Structure-preserving Schur methods for computing square roots of real skew-Hamiltonian matrices
Zhongyun Liu, Yulin Zhang, Carla Ferreira +1
Our contribution is two-folded. First, starting from the known fact that every real skew-Hamiltonian matrix has a real Hamiltonian square root, we give a complete characterization…
