On approximate observability of strongly stable systems
The Hautus test of Russel and Weiss [7] is sufficient for approximate observability if the system is exponentially stable. In this note we show by means of an example that this statement does not hold for strongly stable systems even if the system is modeled by a contraction semigroup.
متن کاملProjecting Sequential Algorithms on Strongly Stable Functions
We relate two sequential models of PCF: the sequential algorithm model due to Berry and Curien and the strongly stable model due to Bucciarelli and the author. More precisely, we show that all the morphisms araising in the strongly stable model of PCF are sequential in the sense that they are the \extensional projections" of some sequential algorithms. We deene a model of PCF where morphisms ar...
متن کاملStrongly stable gyroscopic systems
Here, gyroscopic systems are time-invariant systems for which motions can be characterized by properties of a matrix pencil L(λ) = λ2I + λG − C, where GT = −G and C > 0. A strong stability condition is known which depends only on |G| (= (GT G)1/2 ≥ 0) and C. If a system with coefficients G0 and C satisfies this condition then all systems with the same C and with a G satisfying |G| ≥ |G0| are al...
متن کاملStrongly Stable Networks ∗ by
We analyze the formation of networks among individuals. In particular, we examine the existence of networks that are stable against changes in links by any coalition of individuals. We show that to investigate the existence of such strongly stable networks one can restrict focus on a component-wise egalitarian allocation of value. We show that when such strongly stable networks exist they coinc...
