Positive Semidefinite Matrices
, 2018Positive semidefinite (PSD) and positive definite (PD) matrices are closely connected with Euclidean distance matrices. Accordingly, they play a central role in this monograph. This chapter reviews some of the basic results concerning these matrices.

The -positive semidefinite matrices A such that are nonsingular
Linear and multilinear algebra, 2023This work focuses on the class of $ \mathcal {L} $ L-positive semidefinite matrices A such that $ AA_{(\mathcal {L})}^{(\dag )}-A_{(\mathcal {L})}^{(\dag )}A $ AA(L)(†)−A(L)(†)A is nonsingular, where $ A_{(\mathcal {L})}^{(\dag )} $ A(L)(†) is the ...

Singular value and norm inequalities for positive semidefinite matrices
Linear and multilinear algebra, 2021We prove several singular value and norm inequalities involving generalized commutators and anticommutators of positive semidefinite matrices. These inequalities improve and extend earlier known inequalities, including an inequality due to Davidson and ...
