Superstrong Magnetic Fields in Sunspot Bipolar Light Bridges

open access: yesThe Astrophysical Journal Letters
Recent solar observations of bipolar light bridges (BLBs) in sunspots have, in a few individual cases, revealed magnetic fields up to 8.2 kG, which is at least twice as strong as typical values measured in sunspot umbrae.

A Fourier transform differentiator operator

open access: yesResults in Physics
By utilizing the Fourier transform, we present a practical method for evaluating a function of a derivative applied to any other arbitrary function of a single complex variable.

General Aspects of Line Shapes in Plasmas in the Presence of External Electric Fields

open access: yesAtoms
The present paper discusses a number of topics relevant to line broadening in the presence of periodic oscillatory fields. Specifically, we discuss the applicablility of the expression usually employed to compute the autocorrelation function, the ...

On algebraic function fields with class number three

open access: yes, 2011
Let K/Fq be an algebraic function field with full constant field Fq and genus g. Then the divisor class number hK of K/Fq is the order of the quotient group, D0K /P(K), degree zero divisors of K over principal divisors of K.

The class number of cyclotomic function fields

open access: yes, 1981
Let k be a rational function field over a finite field. Carlitz and Hayes have described a family of extensions of k which are analogous to the collection of cyclotomic extensions {Q(ζm)| m ≥ 2} of the rational field Q.

Color Confinement and Spatial Dimensions in the Complex-Sedenion Space

open access: yesAdvances in Mathematical Physics, 2017
The paper aims to apply the complex-sedenions to explore the wave functions and field equations of non-Abelian gauge fields, considering the spatial dimensions of a unit vector as the color degrees of freedom in the complex-quaternion wave functions ...

The influence of primordial magnetic fields on the spherical collapse model in cosmology

open access: yes, 2018
Despite the ever growing observational evidence for the existence of the large scale magnetic fields, their origin and the evolution are not fully understood. If the magnetic fields are of primordial origin, they result in the generation of the secondary

Extended Genus Fields of Abelian Extensions of Rational Function Fields

open access: yes
In this paper, we obtain the extended genus field of a finite abelian extension of a global rational function field. We first study the case of a cyclic extension of prime power degree. For the general case, we use the fact that the extended genus fields
