Family of wavelet functions on the Galois function base

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
We construct a family of wavelet systems on the Galois function base. We research and prove properties of systems of the built family.

Scaling Metric Measurement Invariance Models

open access: yesMethodology, 2023
This paper aims at clarifying the questions regarding the effects of the scaling method on the discrepancy function of the metric measurement invariance model. We provide examples and a formal account showing that neither the choice of the scaling method

Function Projective Synchronization of Chaotic Systems with a New Kind of Scaling Function

open access: yesChemical Engineering Transactions, 2019
The function projective synchronization of chaotic system with a new kind of scaling function is proposed in this paper. In general, the scaling function factor of function projective synchronization is a function of the time variable.

Superlinear scaling of riverine biogeochemical function with watershed size

open access: yesNature Communications, 2022
River networks play an important role in biogeochemical processes of the earth system. Here the authors show that cumulative river network function increases faster than watershed size for many biogeochemical processes, particularly at higher river flow,

Invariant measures whose supports possess the strong open set property [PDF]

open access: yesOpuscula Mathematica, 2008
Let \(X\) be a complete metric space, and \(S\) the union of a finite number of strict contractions on it. If \(P\) is a probability distribution on the maps, and \(K\) is the fractal determined by \(S\), there is a unique Borel probability measure ...

The universal function in color dipole model

open access: yesPhysics Letters B, 2017
In this work we review color dipole model and recall properties of the saturation and geometrical scaling in this model. Our primary aim is determining the exact universal function in terms of the introduced scaling variable in different distance than ...

Fractal sets satisfying the strong open set condition in complete metric spaces [PDF]

open access: yesOpuscula Mathematica, 2008
Let \(K\) be a Hutchinson fractal in a complete metric space \(X\), invariant under the action \(S\) of the union of a finite number of Lipschitz contractions. The Open Set Condition states that \(X\) has a non-empty subinvariant bounded open subset \(V\)

Some sufficient conditions for the convergence of the cascade algorithm and for the continuity of the scaling function

open access: yesJournal of Numerical Analysis and Approximation Theory, 2003
We define a class of matrices which includes, under some natural assumptions, the matrices \(\mathbf{m}\left( 0\right)\), \(\mathbf{m}\left( 1\right)\) and \(T_{2N-1}\), which are the key matrices of the wavelets theory.

Chaos Synchronization of Financial Chaotic System with External Perturbation

open access: yesDiscrete Dynamics in Nature and Society, 2015
This paper investigates the problem of two kinds of function projective synchronization of financial chaotic system with definite integration scaling function, which are not fully considered in the existing research.

On the relationship of interior-point methods

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
In this paper, we show that the moving directions of the primal-affine scaling method (with logarithmic barrier function), the dual-affine scaling method (with logarithmic barrier function), and the primal-dual interior point method are merely the Newton
