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…

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…
