On the logarithmic probability that a random integral ideal is $\mathscr A$-free

open access: yes, 2017
This extends a theorem of Davenport and Erd\"os on sequences of rational integers to sequences of integral ideals in arbitrary number fields $K$. More precisely, we introduce a logarithmic density for sets of integral ideals in $K$ and provide a formula ...

Three-Parameter Logarithm and Entropy

open access: yesJournal of Function Spaces, 2020
A three-parameter logarithmic function is derived using the notion of q-analogue and ansatz technique. The derived three-parameter logarithm is shown to be a generalization of the two-parameter logarithmic function of Schwämmle and Tsallis as the latter ...

A Logarithmic-Amplitude Polar Diagram [PDF]

open access: yesModeling, Identification and Control, 2001
A polar diagram where the amplitude of the transfer function is on a logarithmic scale, is presented. This gives a one-size-fits-all diagram with no need for zooming in and out, and no need for additional reasoning about infinite-radius encirclements ...

Modeling radial artery pressure waveforms using curve fitting: Comparison of four types of fitting functions

open access: yesArtery Research, 2018
Background: Curve fitting has been intensively used to model artery pressure waveform (APW). The modelling accuracy can greatly influence the calculation of APWs parameters that serve as quantitative measures for assessing the morphological ...

The learning of logarithmic functions by 12th-grade students based on modelling tasks

open access: yesAlteridad : Revista de Educación, 2022
The relevance that the application of what is learned in Mathematics to everyday situations has in student learning has led us to develop an experiment on teaching the logarithmic function using modelling tasks.

Glassy Solutions of the Kardar-Pasrisi-Zhang Equation

open access: yes, 1995
It is shown that the mode-coupling equations for the strong-coupling limit of the KPZ equation have a solution for d>4 such that the dynamic exponent z is 2 (with possible logarithmic corrections) and that there is a delta function term in the height ...

The distributions of sums of the prime indicators with respect to distinct frequencies

open access: yesLietuvos Matematikos Rinkinys, 2004
A characterization of a set of strongly additive functions fx which has the same limit law with respect to ordinary and logarithmic frequencies is obtained. Strongly additive functions which take zero or unit for each prime p are considered.

Logarithmic derivative estimates of meromorphic functions of finite order in the half-plane

open access: yesМатематичні Студії, 2020
We established new sharp estimates outside exceptional sets for of the logarithmic derivatives $\frac{d^ {k} \log f(z)}{dz^k}$ and its generalization $\frac{f^{(k)}(z)}{f^{(j)}(z)}$, where $f$ is a meromorphic function $f$ in the upper half-plane, $k>j ...

Logarithmic Barrier Method Via Minorant Function for Linear Semidefinite Programming

open access: yesAnnales Mathematicae Silesianae, 2023
We propose in this study, a new logarithmic barrier approach to solve linear semidefinite programming problem. We are interested in computation of the direction by Newton’s method and of the displacement step using minorant functions instead of line ...
