Tridiagonal canonical matrices of bilinear or sesquilinear forms and of pairs of symmetric, skew-symmetric, or Hermitian forms
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Tridiagonal canonical forms of square matrices under congruence or *congruence, pairs of symmetric or skew-symmetric matrices under congruence, and pairs of Hermitian matrices under *congruence are given over an algebraically ...

On the Structure of Locally Symmetric Manifolds
(Heldermann Verlag, 2015)
This paper studies structural properties of locally symmetric submanifolds. One of the main result states that a locally symmetric submanifold M of R-n admits a locally symmetric tangential parametrization in an appropriately ...
Extreme spectra realization by real symmetric tridiagonal and real symmetric arrow matrices

Additive representation of symmetric inverse M-matrices and potentials
(Academic Press-Elsevier, 2016)
In this article we characterize the closed cones respectively generated by the symmetric inverse M-matrices and by the inverses of symmetric row diagonally dominant M-matrices. We show the latter has a finite number of ...
A lower bound for the energy of symmetric matrices and graphs
(2017)
The energy of a symmetric matrix is the sum of the absolute values of its eigenvalues. We introduce a lower bound for the energy of a symmetric matrix partitioned into blocks. This bound is related to the spectrum of its ...
