On the Block-Decomposability of 1-Parameter Matrix Flows and Static Matrices
Frank Uhlig
For general complex or real 1-parameter matrix flows and for time-invariant static matrices $A \in \CC_{n,n}$ alike, this paper considers ways to decompose matrix flow…

Coalescing Eigenvalues and Crossing Eigencurves of 1-Parameter Matrix Flows
Frank Uhlig
We investigate the eigenvalue curves of 1-parameter hermitean and general complex or real matrix flows in light of their geometry and the uniform decomposability of f…
