In this work, we investigate inequalities of singular values and unitarily invariant norms for sums and products of matrices. First, we give an another more concise and clear proof to inequality ...

Abstract: Ant colony optimization (ACO) algorithm is a swarm intelligence approach widely applied to real-world optimization problems. However, how to access the convergence status of ACO remains a ...

Matrices with displacement structure, such as Pick, Vandermonde, and Hankel matrices, appear in a diverse range of applications. In this paper, we use an extremal problem involving rational functions ...
