Jesse Jääsaari

摘要:

我们考虑群$\mathrm{SL}_3(\mathbb Z)$的Hecke-Maass尖点形式的傅里叶系数的符号变化。当基本形式是自对偶的,我们表明,有$\gg_\varepsilon X^{5/6-\varepsilon}$符号之间的系数$\{A(m,1)\}_{m\leq X}$的变化,并有一个积极的比例,许多自对偶形式的符号变化。类似的结果有关的正比例的符号变化也持有的通用$\mathrm{GL}_3$尖点形式的实值系数$A(m,m)$,一个结果,这是基于一个新的有效的Sato-Tate型定理的一个家庭的$\mathrm{GL}_3$尖点形式,我们建立。另外,在Ramanujan-Petersson猜想下,研究了傅里叶系数的非零性.

英文摘要:

We consider sign changes of Fourier coefficients of Hecke-Maass cusp forms for the group $\mathrm{SL}_3(\mathbb Z)$. When the underlying form is self-dual, we show that there are $\gg_\varepsilon X^{5/6-\varepsilon}$ sign changes among the coefficients $\{A(m,1)\}_{m\leq X}$ and that there is a positive proportion of sign changes for many self-dual forms. Similar result concerning the positive proportion of sign changes also hold for the real-valued coefficients $A(m,m)$ for generic $\mathrm{GL}_3$ cusp forms, a result which is based on a new effective Sato-Tate type theorem for a family of $\mathrm{GL}_3$ cusp forms we establish. In addition, non-vanishing of the Fourier coefficients is studied under the Ramanujan-Petersson conjecture.
