Modular Invariant of Quantum Tori II: The Golden Mean [PDF]

open access: yes, 2012
In our first article in this series ("Modular Invariant of Quantum Tori I: Definitions Nonstandard and Standard" arXiv:0909.0143) a modular invariant of quantum tori was defined.

Primitive and totally primitive Fricke families with applications

open access: yes, 2016
We introduce the primitivity of Fricke families, and give some examples. As its application, we first construct generators of the function field of the modular curve of level $N$ in terms of Fricke functions and Siegel functions, respectively ...

An elementary approach to toy models for D. H. Lehmer's conjecture

open access: yes, 2010
In 1947, Lehmer conjectured that the Ramanujan's tau function $\tau (m)$ never vanishes for all positive integers $m$, where $\tau (m)$ is the $m$-th Fourier coefficient of the cusp form $\Delta_{24}$ of weight 12.

Recurrence relations satisfied by some arithmetic groups

open access: yesOpen Mathematics
Recently, recurrence relations satisfied by the modular traces of the Hauptmodul for Γ0(N){\Gamma }_{0}\left(N) of genus zero have been established. However, these relations do not determine all values of the modular traces.

Rigid realizations of modular forms in Calabi--Yau threefolds

open access: yes, 2017
We construct examples of modular rigid Calabi--Yau threefolds, which give a realization of some new weight 4 cusp ...

On the Mahler measure of $1+X+1/X+Y+1/Y$

open access: yes, 2011
We prove a conjectured formula relating the Mahler measure of the Laurent polynomial $1+X+X^{-1}+Y+Y^{-1}$, to the $L$-series of a conductor 15 elliptic curve.Comment: 18 pages, Fixed typos in Lemmas 3 and

Zeros of weakly holomorphic modular forms of levels 2 and 3

open access: yes, 2013
Let $M_k^\sharp(N)$ be the space of weakly holomorphic modular forms for $\Gamma_0(N)$ that are holomorphic at all cusps except possibly at $\infty$. We study a canonical basis for $M_k^\sharp(2)$ and $M_k^\sharp(3)$ and prove that almost all modular ...

Birch and Swinnerton-Dyer conjecture in the complex multiplication case and the congruent number problem

open access: yes, 2019
For an elliptic curve $E$ over $K$, the Birch and Swinnerton-Dyer conjecture predicts that the rank of Mordell-Weil group $E(K)$ is equal to the order of the zero of $L(E_{/ K},s)$ at $s=1$.

On non-vanishing and sign changes of the Fourier coefficients of Hilbert cusp forms

open access: yes, 2017
In this article, we study (simultaneous) non-vanishing, (simultaneous) sign changes of Fourier coefficients of (two) Hilbert cusp forms ...
