CODIMENSION TWO CYCLES IN IWASAWA THEORY AND ELLIPTIC CURVES WITH SUPERSINGULAR REDUCTION

open access: yesForum of Mathematics, Sigma, 2019
A result of Bleher, Chinburg, Greenberg, Kakde, Pappas, Sharifi and Taylor has initiated the topic of higher codimension Iwasawa theory. As a generalization of the classical Iwasawa main conjecture, they prove a relationship between analytic objects (a ...

The finiteness of the Tate–Shafarevich group over function fields for algebraic tori defined over the base field

open access: yesComptes Rendus. Mathématique
Let $K$ be a field and $V$ be a set of rank one valuations of $K$. The corresponding Tate–Shafarevich group of a $K$-torus $T$ is $\Sha (T, V) = \ker (H^1(K, T) \rightarrow \prod _{v\,\in \,V} H^1(K_v, T))$.

A Semi-Linear Elliptic Model for a Circular Membrane MEMS Device Considering the Effect of the Fringing Field

open access: yesSensors, 2021
In this study, an accurate analytic semi-linear elliptic differential model for a circular membrane MEMS device, which considers the effect of the fringing field on the membrane curvature recovering, is presented.

p-Algebras over an algebraic function field over a perfect field

open access: yesJournal of Algebra, 1986
Verf. beweist folgenden Satz: Sei K ein algebraischer Funktionen-Körper in r Variablen über einem vollkommenen Körper. Jede p-Algebra A über K ist Brauer-äquivalent dem Kroneckerprodukt von r zyklischen Divisionsalgebren \(D_ i\) mit Exponent \(D_ i=Index D_ i\) und Exponent \(D_ i\leq Exponent A\). Für \(r=1\) ist das ein bekannter Satz von A.

Excellent Nonlinear Codes From Algebraic Function Fields

open access: yesIEEE Transactions on Information Theory, 2005
The Gilbert-Varshamov (GV) bound for asymptotic families of codes over F/sub q/ has been improved by Tsfasman, Vla/spl breve/dut$80, and Zink (TVZ) in 1982, and only recently further improvements have been obtained by Xing, Elkies, and Niederreiter-O/spl uml/zbudak, by considering also nonlinear codes.

Gauge coupling field, currents, anomalies and N=1 super-Yang–Mills effective actions

open access: yesNuclear Physics B, 2017
Working with a gauge coupling field in a linear superfield, we construct effective Lagrangians for N=1 super-Yang–Mills theory fully compatible with the expected all-order behavior or physical quantities.

Application of the Complex Variable Function Method to SH-Wave Scattering Around a Circular Nanoinclusion

open access: yesAdvances in Mathematical Physics, 2019
This paper focuses on analyzing SH-wave scattering around a circular nanoinclusion using the complex variable function method. The surface elasticity theory is employed in the analysis to account for the interface effect at the nanoscale. Considering the

On a realization of {β}-expansion in QCD

open access: yesJournal of High Energy Physics, 2017
We suggest a simple algebraic approach to fix the elements of the {β}-expansion for renormalization group invariant quantities, which uses additional degrees of freedom.
