Let $cmathcal{E}_cperp$ be the natural orthogonal-complement effective subspace defined above, and let $coverline{\bm p}$ be the vector defined in Corollary corresponding to…

Let $\Sigma\subset\mathbb{C}$ be the set of spectral points, and let $V_0$ and $Q_0$ be the solution basis and Lanczos matrix corresponding to the background $q_0=0$. Let $T$ be th…

Minimality conjecture. If $(\cC(s), \cK(s))$ is $\C^n$--observable and $(\cK(s), \cB(s))$ is $\C^n$--reachable, then there is no lower-order realization, constructible via Petrov--…
