Estimation of the maximum multiplicity of an eigenvalue in terms of the vertex degrees of the graph of a matrix.

Euclidean and circum-Euclidean distance matrices: characterizations and linear preservers.
Expansion of (n -1)-Rowed Sub-Determinants.
Extreme Points of a Convex Subset of the Cone of Positive Semidefinite Matrices.
Factorizable matrices
We study square matrices which are products of simpler factors with the property that any ordering of the factors yields a matrix cospectral with the given matrix. The results generalize those obtained previously by the authors.
