Jacobi Theta Functions over Number Fields [PDF]

Monatshefte 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

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

On solving norm equations in global function fields

Journal 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

Physics 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

Monomial Dynamical Systems of Dimension One over Finite Fields

, 2011
In this paper we study the monomial dynamical systems of dimension one over finite fields from the viewpoints of arithmetic and graph theory. We give formulas for the number of periodic points with period r and cycles with length r.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

On construction of correlation numbers in super minimal Liouville gravity in the Ramond sector

Journal of High Energy Physics
We study the construction of correlation numbers in super minimal Liouville gravity. In particular, we construct the fundamental physical fields in the Ramond sector and compute the three-point correlation number involving two physical fields in the ...

Class number approximation in cubic function fields

Contributions 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.

Determinant formulas for class numbers in function fields [PDF]

Mathematics of Computation, 2004
In this paper, by extending Kucera’s idea to the function field case, we obtain several determinant formulas involving the real class number and the relative class number of any subfield of cyclotomic function fields. We also provide several examples using these determinant formulas.
