Related to ergodic: Ergodic hypothesis


Of or relating to a system or process whose overall statistical properties can be determined by analysis of a sufficiently large sample of the states of one of its constituents or instances averaged over time.

[German Ergode, a set of points in a space with the property that all points will be included in a trajectory with equal frequency given a sufficient large number of trajectories (coined by Ludwig Eduard Boltzmann from Greek ergon, work; see werg- in Indo-European roots + Greek hodos, way, path) + -ic.]

pertaining to the condition that, in an interval of sufficient duration, a system will return to states that are closely similar to previous ones: the basis of statistical methods used in modern dynamics and atomic theory.

Further, we investigate how transition dynamics shifted the equilibrium levels of employment and unemployment over time and across space, by deriving the ergodic distributions related to the observed labour market transitions in each country over the period.
In this section, key statistical properties of the model, e.g., the spatial cross-correlation function (CCF), temporal autocorrelation function (ACF), Wigner-Ville spectrum, and ergodic capacity under non-isotropic scattering conditions considering the impact of velocity variations will be derived.
Bou-Rabee and Vanden-Eijnden propose a strategy for simulating stochastic differential equations, adopting an approach that is more tailored to the probabilistic structure of the solution in order to design stable and (weakly) accurate schemes for their simulation that are both provably ergodic when the underlying stochastic differential equation is, and faithful to the geometry of their domain of integration.
The random periodic scenario is excluded from the current ergodic theory even in the case of Markov chains.
In this paper, the system performance (in the term the achievable throughput, the outage probability, ergodic capacity) of a two-way decode-and-forward two-way relaying network over Rician fading channel under the hardware impairment effect is proposed, analysed and demonstrated in details.
With the aim of classifying objective and subjective expressions, a discrete ergodic HMM was employed.

Nonlinear operator theory applies to diverse nonlinear problems in many areas such as differential equations, nonlinear ergodic theory, game theory, optimization problems, control theory, variational inequality problems, equilibrium problems, and split feasibility problems.
This action is known to be ergodic (see for example [FTP82] and [FTP83]), but since the measure is not preserved, no theorem on the convergence of means of the corresponding unitary operators had been proved.
