Exploring invariant sets and invariant measures
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1997 We propose a method to explore invariant measures of dynamical systems. The method is based on numerical tools which directly compute invariant sets using a subdivision technique, and invariant measures by a discretization of the Frobenius-Perron ...

Shift-invariant measures on infinite-dimensional spaces: Integrable functions and random walks
Учёные записки Казанского университета: Серия Физико-математические науки, 2018 Averaging of random shift operators on a space of the square integrable by shift-invariant measure complex-valued functions on linear topological spaces has been studied. The case of the l∞ space has been considered as an example.

Measures of concordance determined by D4-invariant copulas [PDF]
International Journal of Mathematics and Mathematical Sciences, 2004 A continuous random vector (X,Y) uniquely determines a copula C:[0,1]2→[0,1] such that when the distribution functions of X and Y are properly composed into C, the joint distribution function of (X,Y) results.

Surplus-invariant risk measures [PDF]
Mathematics of Operations Research, 2020 This paper presents a systematic study of the notion of surplus invariance, which plays a natural and important role in the theory of risk measures and capital requirements.

Editorial: Measurement Invariance [PDF]
Frontiers in Psychology, 2015 Multi-item surveys are frequently used to study scores on latent factors, like human values, attitudes, and behavior. Such studies often include a comparison, between specific groups of individuals or residents of different countries, either at one or multiple points in time (i.e., a cross-sectional or a longitudinal comparison or both).

RECURRENCE AND THE EXISTENCE OF INVARIANT MEASURES [PDF]
The Journal of Symbolic Logic, 2021 AbstractWe show that recurrence conditions do not yield invariant Borel probability measures in the descriptive set-theoretic milieu, in the strong sense that if a Borel action of a locally compact Polish group on a standard Borel space satisfies such a condition but does not have an orbit supporting an invariant Borel probability measure, then there ...

, 2015 Multi-item surveys are frequently used to study scores on latent factors, like human values, attitudes and behavior. Such studies often include a comparison, between specific groups of individuals, either at one or multiple points in time. If such latent factor means are to be meaningfully compared, the measurement structures including the latent ...

Quantum Invariant Measures [PDF]
Communications in Mathematical Physics, 2001 We derive an explicit expression for the Haar integral on the quantized algebra of regular functions C_q[K] on the compact real form K of an arbitrary simply connected complex simple algebraic group G. This is done in terms of the irreducible *-representations of the Hopf *-algebra C_q[K]. Quantum analogs of the measures on the symplectic leaves of the

Invariance measures for neural networks
Applied Soft Computing, 2023 Invariances in neural networks are useful and necessary for many tasks. However, the representation of the invariance of most neural network models has not been characterized. We propose measures to quantify the invariance of neural networks in terms of their internal representation.
