On the Approximation of Koopman Spectra for Measure Preserving Transformations [PDF]
For the class of continuous, measure-preserving automorphisms on compact metric spaces, a procedure is proposed for constructing a sequence of finite-dimensional approximations to the associated Koopman operator on a Hilbert space. These finite-dimensional approximations are obtained from the so-called "periodic approximation" of the underlying ...

Models for measure preserving transformations
This is an attractive survey of some recent work of the author, Dan Rudolph and Benjamin Weiss on classification problems in ergodic theory from the point of view of set theory. A particular focus is how statements about the complexity or the genericity of a dynamical property (for example, mixing, weak-mixing, zero entropy, and so on) or a dynamically

Some Observations on Dirac Measure-Preserving Transformations and their Results [PDF]
Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space.

In supervised deep learning, learning good representations for remote-sensing images (RSI) relies on manual annotations. However, in the area of remote sensing, it is hard to obtain huge amounts of labeled data.

Observational Modeling of the Kolmogorov-Sinai Entropy [PDF]
In this paper, Kolmogorov-Sinai entropy is studied using mathematical modeling of an observer $ Theta $. The relative entropy of a sub-$ sigma_Theta $-algebra having finite atoms is defined and then the ergodic properties of relative semi-dynamical ...

Subadditive Pre-Image Variational Principle for Bundle Random Dynamical Systems
A central role in the variational principle of the measure preserving transformations is played by the topological pressure. We introduce subadditive pre-image topological pressure and pre-image measure-theoretic entropy properly for the random bundle ...

Experimental analysis of wavelet decomposition on edge detection; pp. 284–298 [PDF]
The influence of different wavelet transformations and decomposition on edge detection was examined, using convenient operators to images of various complexities. Berkeley Segmentation Database images with the corresponding ground truth were used.

A decomposition of multicorrelation sequences for commuting transformations along primes
A decomposition of multicorrelation sequences for commuting transformations along primes, Discrete Analysis 2021:4, 27 pp. Szemerédi's theorem asserts that for every positive integer $k$ and every $\delta>0$ there exists $n$ such that every subset of $\

Ergodicity Space for Measure-Preserving Transformations [PDF]
We introduce the concept of ergodicity space of a measure-preserving transformation and will present some of its properties as an algebraic weight for measuring the size of the ergodicity of a measure-preserving transformation. We will also prove the invariance of the ergodicity space under conjugacy of dynamical systems.
