Abstract

In this chapter we consider minimal, finite-dimensional stochastic systems both in discrete and continuous time. We show how the zero structure of the minimal spectral factors relate to the splitting subspace geometry of stationary stochastic models and to the corresponding algebraic Riccati inequality. We introduce the notion of output-induced subspace of a minimal Markovian splitting subspace, which is the stochastic analogue of the output-nulling subspace in geometric control theory [23, 316]. Through this concept the analysis can be made coordinate-free, and straightforward geometric methods can be applied.
