-adic Chowla-Selberg formula over function fields

Fu-Tsun Wei

Let be a finite place of a rational function field with finite constant field. We establish an Ogus-type -adic Chowla-Selberg formula for -motives with "complex multiplic…

Algebraic Relations among Special Gamma Values and the Chowla-Selberg Phenomenon over Function Fields

Fu-Tsun Wei

The aim of this paper is to determine all algebraic relations among various special gamma values over function fields, and prove a Chowla-Selberg-type formula for quasi-periods of…

Function Field Analogue of Shimura's Conjecture on Period Symbols

W. Dale Brownawell, Chieh-Yu Chang, Matthew A. Papanikolas +1

In this paper we introduce the notion of Shimura's period symbols over function fields in positive characteristic and establish their fundamental properties. We further formulate a…

On class number relations, intersections, and GL(2)-tale over the function field side

Jia-Wei Guo, Fu-Tsun Wei

The aim of this paper is to study class number relations over function fields and the intersections of Hirzebruch-Zagier type divisors on the Drinfeld-Stuhler modular surfaces. The…

Sturm-type bounds for modular forms over functions fields

Cécile Armana, Fu-Tsun Wei

In this paper, we obtain two analogues of the Sturm bound for modular forms in the function field setting. In the case of mixed characteristic, we prove that any harmonic cochain i…

Drinfeld discriminant function and Fourier expansion of harmonic cochains

Mihran Papikian, Fu-Tsun Wei

Let be the completion of at . We develop a theory of Fourier expansions for harmonic cochains on the edges of the Bruhat-T…

On Kronecker terms over global function fields

Fu-Tsun Wei

We establish a general Kronecker limit formula of arbitrary rank over global function fields with Drinfeld period domains playing the role of upper-half plane. The Drinfeld-Siegel…

Generalized Jacobians of modular and Drinfeld modular curves

Fu-Tsun Wei, Takao Yamazaki

We consider the generalized Jacobian of the modular curve of level with respect to a reduced divisor consisting of all cusps. Supposing is square f…

Waldspurger formula over function fields

Chih-Yun Chuang, Fu-Tsun Wei

In this paper, we derive a function field version of the Waldspurger formula for the central critical values of the Rankin-Selberg L-functions. This formula states that the central…

On derivatives of Siegel-Eisenstein series over global function fields

Fu-Tsun Wei

The aim of this article is to study the derivative of "incoherent" Siegel-Eisenstein series on symplectic groups over function fields. By the Siegel-Weil formula for "coherent" Sie…

The rational torsion subgroups of Drinfeld modular Jacobians and Eisenstein pseudo-harmonic cochains

Mihran Papikian, Fu-Tsun Wei

Let be a square-free ideal of . We study the rational torsion subgroup of the Jacobian variety of the Drinfeld modular curve $X_0(\frak{…

On the Eisenstein ideal over function fields

Mihran Papikian, Fu-Tsun Wei

We study the Eisenstein ideal of Drinfeld modular curves of small levels, and the relation of the Eisenstein ideal to the cuspidal divisor group and the component groups of Jacobia…

The Eisenstein ideal and Jacquet-Langlands isogeny over function fields

Mihran Papikian, Fu-Tsun Wei

Let and be two distinct prime ideals of . We use the Eisenstein ideal of the Hecke algebra of the Drinfeld modular curve $X_0(\frak{p}\frak{q…

Class numbers of central simple algebras over global function fields

Fu-Tsun Wei, Chia-Fu Yu

Let be a global function field together with a place , and the subring of functions regular outside . In this paper we present an effective method to evalua…

Mass formula of division algebras over global function fields

Fu-Tsun Wei, Chia-Fu Yu

In this paper we give two proofs of the mass formula for definite central division algebras over global function fields, due to Denert and Van Geel. The first proof is based on a c…

The Singly Periodic Genus-One Helicoid

David Hoffman, Hermann Karcher, Fusheng Wei

We prove the existence of a complete, embedded, singly periodic minimal surface, whose quotient by vertical translations has genus one and two ends. The existence of this surface w…
