Robust Weak Ergodicity And Stable Ergodicity

Acta Mathematica Scientia, 2013
Abstract In this paper, we define robust weak ergodicity and study the relation between robust weak ergodicity and stable ergodicity for conservative partially hyperbolic systems. We prove that a C r ( r > 1) conservative partially hyperbolic diffeomorphism is stably ergodic if it is robustly weakly ergodic and has positive (or negative) central ...

Some Nonlinear Weak Ergodic Theorems

SIAM Journal on Mathematical Analysis, 1990
Let C be a cone with nonempty interior in a Banach space and, for $j \geqq 1$, let $f_j :\mathop C\limits^ \circ \to \mathop C\limits^ \circ $ be a sequence of maps.

Ergodic measures are of weak product type

Mathematical Proceedings of the Cambridge Philosophical Society, 1985
Abstract There are many results which discuss ergodicity in terms of approximate product properties. Here we work throughout with stochastically independent σ-algebras (ℰ, ℱ are independent of μ if μ (E ∩ F) =μ (E)μ(F) for all E ∊ ℰ,F ∊ ℱ), to obtain an exact product property characteristic of (a large class of) ergodic measures. The ideas are based

Weak ergodicity in non-homogeneous Markov chains

Mathematical Proceedings of the Cambridge Philosophical Society, 1958
ABSTRACTThe paper deals with weak ergodicity, i.e. the tendency for a chain to ‘forget’ the distant past. This may occur in non-homogeneous chains even if the probabilities of being in a given state do not tend to a limit as the number of trials increases.Investigation of the general conditions of weak ergodicity leads to the definition of a special ...

A decision theoretical characterization of weak ergodicity

Zeitschrift f�r Wahrscheinlichkeitstheorie und Verwandte Gebiete, 1978
The relation between the ergodic coefficient and deficiency relative to the least informative experiment is investigated. The result is applied to nonhomogeneous Markov chains (NMC's). Our main result can be described as follows: Given an NMC, define the experiments ℰn(j) for n≧1 consisting in observing the (n+j)-th state of the chain, the j-th state ...

An experimental study of weak ergodicity in human populations

Theoretical Population Biology, 1976
Abstract In demography, weak ergodicity is usually taken to mean the tendency of an age distribution to “forget” its past, or, equivalently, the essential dependence of current age distribution on only a recent history of age-specific vital rates.
