چکیده مقاله:

‎This paper presents two main results that the singular values of the Hadamard product of normal matrices $A_i$ are weakly log-majorized by the singular values of the Hadamard product of $|A_{i}|$ and the singular values of the sum of normal matrices $A_i$ are weakly log-majorized by the singular values of the sum of $|A_{i}|$‎. ‎Some applications to these inequalities are also given‎. ‎In addition‎, ‎several related and new inequalities are obtained‎.

Inequalities for Singular Values of Positive Semidefinite Block Matrices

In this paper, we first give a lower and upper bounds for singular values of a 2×2 positive semidefinite block matrices. Then, we give some weakly majorization inequalities of singular values positive semidefinite block matrices. Also, we present inequalities involving the direct sum and sum of positive semidefinite matrices.

On the singular values of random matrices

We present an approach that allows one to bound the largest and smallest singular values of an N × n random matrix with iid rows, distributed according to a measure on R that is supported in a relatively small ball and linear functionals are uniformly bounded in Lp for some p > 8, in a quantitative (non-asymptotic) fashion. Among the outcomes of this approach are optimal estimates of 1±c √ n/N ...

On structured singular values of reciprocal matrices

Computing the structured singular value (or ) is a bottleneck of the robustness analysis and synthesis of control systems. In this paper, it is shown that is identical to the maximum singular value for an important class of matrices called reciprocal, which re ects the intrinsic symmetry of physical world.
