Abstract
We study the behavior of Hermitian solutions, especially the maximal ones, of algebraic Riccati equations whose coefficients depend on real parameters. The cases of analytic dependence on one parameter andC′ dependence (0≤r≤∞) on many parameters are considered. The basic assumption made is stabilizability.
