A Limit Set Trichotomy for Order-preserving Random Systems
نویسنده
چکیده
We study the asymptotic behavior of order-preserving (or monotone) random systems which have an additional concavity property called sub-linearity (or subhomogeneity), frequently encountered in applications. Sublinear random systems are contractive with respect to the part metric, hence random equilibria are unique and asymptotically stable in each part of the cone. Our main result is a random limit set trichotomy, stating that in a given part either (i) all orbits are unbounded, or (ii) all orbits are bounded but their closure reaches out to the boundary of the part, or (iii) there exists a unique, globally attracting equilibrium. Several examples, including aane and cooperative systems, are given.

Cooperative Random and Stochastic Diierential Equations
This is a systematic study of order-preserving (or monotone) random dynamical systems which are generated by cooperative random or stochas-tic diierential equations. Our main results concern the long-term behavior of these systems, in particular the existence of equilibria and attractors and a limit set trichotomy theorem. Several applications (models of the control of the protein synthesis in ...
متن کاملRandom Graph Directed Markov Systems
We introduce and explore random conformal graph directed Markov systems governed by measure-preserving ergodic dynamical systems. We first develop the symbolic thermodynamic formalism for random finitely primitive subshifts of finite type with a countable alphabet (by establishing tightness in a narrow topology). We then construct fibrewise conformal and invariant measures along with fibrewise ...
متن کاملTrichotomy for Dynamical Systems in Banach Spaces
We construct a framework for the study of dynamical systems that describe phenomena from physics and engineering in infinite dimensions and whose state evolution is set out by skew-evolution semiflows. Therefore, we introduce the concept of ω-trichotomy. Characterizations in a uniform setting are proved, using techniques from the domain of nonautonomous evolution equations with unbounded coeffi...
متن کاملThe Trichotomy of Knowledge: A Basis for Knowledge Management
An information system is a representation of a real or virtual system. We assume that the design of an information system starts with a set of ontological constructs that are then mapped to a set of grammatical constructs. Given this assumption then an ontology of knowledge is a necessary starting point for conceptual modeling in the design of knowledge-based systems. This paper proposes a thre...
متن کاملON THE SYSTEM OF LEVEL-ELEMENTS INDUCED BY AN L-SUBSET
This paper focuses on the relationship between an $L$-subset and the system of level-elements induced by it, where the underlying lattice $L$ is a complete residuated lattice and the domain set of $L$-subset is an $L$-partially ordered set $(X,P)$. Firstly, we obtain the sufficient and necessary condition that an $L$-subset is represented by its system of level-elements. Then, a new representat...
