模形式的傅里叶系数的同时非零性和符号变化

Simultaneous non-vanishing and sign changes of Fourier coefficients of modular forms

Moni Kumari, M. Ram Murty

摘要:

本文给出了两个模形式的傅里叶系数同时非零和同时变号的一些结果。更确切地说,给定两个模形式$f$和$g$的傅里叶系数$a_n$和$b_n$分别,我们考虑以下问题:存在无穷多个素数$p$,使$a_p b_p\neq 0$ ;同时非零的短时间间隔和等差数列;同时在短时间间隔的符号变化。

英文摘要:

In this article, we give some results on simultaneous non-vanishing and simultaneous sign-changes for the Fourier coefficients of two modular forms. More precisely, given two modular forms $f$ and $g$ with Fourier coefficients $a_n$ and $b_n$ respectively, we consider the following questions: existence of infinitely many primes $p$ such that $a_p b_p\neq 0$; simultaneous non-vanishing in the short intervals and in arithmetic progressions; simultaneous sign changes in short intervals.
