Fronsdal fields from gauge functions in Vasiliev’s higher spin gravity

open access: yesJournal of High Energy Physics, 2019
In this paper, we revisit a number of issues in Vasiliev’s theory related to gauge functions, ordering schemes, and the embedding of Fronsdal fields into master fields.

Integrals and series related to propagators of neural and haemodynamic waves

open access: yesRoyal Society Open Science, 2021
The propagator, or Green function, of a class of neural activity fields and of haemodynamic waves is evaluated exactly. The results enable a number of related integrals to be evaluated, along with series expansions of key results in terms of Bessel ...

Class number approximation in cubic function fields

open access: yesContributions to Discrete Mathematics, 2007
We develop explicitly computable bounds for the order of the Jacobian of a cubic function field. We use approximations via truncated Euler products and thus derive effective methods of computing the order of the Jacobian of a cubic function field. Also, a detailed discussion of the zeta function of a cubic function field extension is included.

Jacobi Theta Functions over Number Fields [PDF]

open access: yesMonatshefte f�r Mathematik, 2004
Eichler and Zagier developed a theory of holomorphic Jacobi forms and showed that Jacobi theta functions corresponding to positive definite quadratic forms are examples of such forms. N.-P. Skoruppa introduced the notion of skew-holomorphic Jacobi forms and presented examples using Jacobi theta functions corresponding to indefinite quadratic forms with

The genus fields of Kummer function fields

open access: yes, 2003
In this paper, we give a definition of genus field of function field with one variable over finite fields. And we explicitly describe the genus fields of Kummer function fields.

Mean Value of the Class Number in Function Fields Revisited [PDF]

open access: yes, 2018
In this paper an asymptotic formula for the sum ∑ (1, χ) is established for the family of quadratic Dirichlet L-functions over the rational function field over a finite field Fq with q fixed.

On solving norm equations in global function fields

open access: yesJournal of Mathematical Cryptology, 2009
The potential of solving norm equations is crucial for a variety of applications of algebraic number theory, especially in cryptography. In this article we develop general effective methods for that task in global function fields for the first time.

A method for BPS equations of vortices

open access: yesPhysics Letters B, 2017
We develop a new method for obtaining the BPS equations of static vortices motivated by the results of the On-Shell method on the standard Maxwell–Higgs model and its Born–Infeld–Higgs model [1]. Our method relies on the existence of what we shall call a
