Supports for minimal hermitian matrices
(Elsevier Science Inc, 2020-01)
We study certain pairs of subspaces V and W of C^n we call supports that consist of eigenspaces of the eigenvalues ±‖M‖ of a minimal hermitian matrix M(‖M‖ ≤‖M+D‖ for all real diagonals D). For any pair of orthogonal ...

CONTROL SYSTEMS ON FLAG MANIFOLDS AND THEIR CHAIN CONTROL SETS
(2017)
A right-invariant control system Sigma on a connected Lie group G induce affine control systems Sigma(Theta) on every flag manifold F-Theta = G/P-Theta. In this paper we show that the chain control sets of the induced ...
