Investigating Monogenity in a Family of Cyclic Sextic Fields

open access: yesMathematics
Jones characterized, among others, monogenity of a family of cyclic sextic polynomials. Our purpose is to study monogenity of the family of corresponding sextic number fields.

On common index divisors and monogenity of septic number fields defined by trinomials of type $x^7+ax^5+b$ [PDF]

open access: yesMathematica Bohemica
Let $K $ be a septic number field generated by a root $\theta$ of an irreducible polynomial $ F(x)= x^7+ax^5+b \in\mathbb Z[x]$. In this paper, we explicitly characterize the index $i(K)$ of $K$.

SOME PROPERTIES OF OPERATOR EXPONENT

open access: yesUral Mathematical Journal, 2018
We study operators given by series, in particular, operators of the form \(e^B=\sum\limits_{n=0}^{\infty}{B^n}/{n!},\) where \(B\) is an operator acting in a Banach space \(X\). A corresponding example is provided.

On symbology and differential equations of Feynman integrals from Schubert analysis

open access: yesJournal of High Energy Physics, 2023
We take the first step in generalizing the so-called “Schubert analysis”, originally proposed in twistor space for four-dimensional kinematics, to the study of symbol letters and more detailed information on canonical differential equations for Feynman ...

Adaptive Units and Control Systems of Power Semiconductor Converters on the Basis of Integrating Scanning Conversion

open access: yesProcedia Engineering, 2015
AbstractOne of the possible solutions leading to higher interference immunity and electromagnetic compatibility of control systems of power semiconductor converters (SC) due to the usage of integrating scanning conversion is given. Integrating adaptive synchronizing units, phase shifting adevices and analog-digital converters, which are distinguished ...

Unsteady turbulence cascades [PDF]

open access: yes, 2016
We have run a total of 311 Direct Numerical Simulations (DNS) of decaying three-dimensional Navier-Stokes turbulence in a periodic box with values of the Taylor length-based Reynolds number up to about 300 and an energy spectrum with a wide wavenumber ...
