Investigating multiwavelength lognormality with simulations— case of Mrk 421 [PDF]

open access: yes, 2020
Blazars are highly variable and display complex characteristics. A key characteristic is the flux probability distribution function or flux PDF whose shape depends upon the form of the underlying physical process driving variability.

The Main Properties of q-Functions

open access: yesНаукові вісті Національного технічного університету України "Київський політехнічний інститут", 2017
Background.  The new generalization of the function of complex variable (q-function) is considered, its main properties are investigated. Such distributions have a special place among the special functions due to their widespread use in many areas of ...

Fixed Point Property of Variable Exponent Cesàro Complex Function Space of Formal Power Series under Premodular

open access: yesJournal of Function Spaces, 2022
We have defined the variable exponent of the Cesàro complex function space of formal power series. We have constructed the prequasi-ideal generated by s-numbers and this new space of complex functions. We present some topological and geometric structures

Gaps in Taylor series of algebraic functions [PDF]

open access: yes, 2014
Let $f$ be a rational function on an algebraic curve over the complex numbers. For a point $p$ and local parameter $x$ we can consider the Taylor series for $f$ in the variable $x$.

Complex Correntropy with Variable Center: Definition, Properties, and Application to Adaptive Filtering

open access: yesEntropy, 2020
The complex correntropy has been successfully applied to complex domain adaptive filtering, and the corresponding maximum complex correntropy criterion (MCCC) algorithm has been proved to be robust to non-Gaussian noises.

Applying machine learning to the problem of choosing a heuristic to select the variable ordering for cylindrical algebraic decomposition [PDF]

open access: yes, 2014
Cylindrical algebraic decomposition(CAD) is a key tool in computational algebraic geometry, particularly for quantifier elimination over real-closed fields. When using CAD, there is often a choice for the ordering placed on the variables.

The Spectrum of Mapping Ideals of Type Variable Exponent Function Space of Complex Variables with Some Applications

open access: yesJournal of Function Spaces, 2021
The topological and geometric behaviors of the variable exponent formal power series space, as well as the prequasi-ideal construction by s-numbers and this function space of complex variables, are investigated in this article. Upper bounds for s-numbers

Surface Green's functions in finite plane elastostatics of harmonic materials

open access: yesArchives of Mechanics, 2018
The closed-form representations of surface Green’s functions corresponding to the action of a concentrated force applied at the boundary of a region occupied by a particular class of compressible hyperelastic materials of harmonic type, has been derived.

The stresses components in position and time of weakened plate with two holes conformally mapped into a unit circle by a conformal mapping with complex constant coefficients

open access: yesAIMS Mathematics, 2023
In this paper, an infinite elastic plate weakened by two holes are considered and the complex variable method is used to derive a closed form of Gaursat functions for the first and second fundamental problems with variant time. The holes, in all previous
