Unconditional Bounds for Two, Three and Four Consecutive Moderate Gaps between Zeros of the Riemann Zeta Function

César Angón, Erick Ross, Ze Sen Tang +1

We prove unconditional positive-proportion results for consecutive moderate gaps between zeros of the Riemann zeta function. More precisely, for every fixed $0<c\leq 1/4$, the lo…

Only finitely many modular Jacobians are supersingular modulo a given prime

Aarya J. Kumar, Sargam Mondal, Erick Ross +1

In this paper, we study supersingularity of modular Jacobians $J_{0} (N)$ and abelian varieties $A_{f}$ of $GL_{2}$ -type from both the vertical perspective (where the prime $p$ …

Effective Hecke eigenvalue equidistribution over the Atkin--Lehner subspaces

Aarya J. Kumar, Sargam Mondal, Erick Ross +1

For a fixed prime $p$ , let $μ_{p}$ denote the $p$ -adic Plancherel measure. Then the first main goal of this paper is to prove effective (and moreover explicit) $μ_{p}$ -equidistribution…

On murmurations

Timothy Nelson, Erick Ross, Maya Wassercug +1

In the recent paper ``Murmurations", Zubrilina showed that the Fourier coefficients of modular forms follow a certain murmuration pattern. The proof given in ``Murmurations" procee…

Asymptotics of Hecke polynomial coefficients on the Atkin-Lehner eigenspaces

Timothy Nelson, Erick Ross, Maya Wassercug +1

Let $S_{k}^{σ} (N)$ denote the space of cusp forms of level $N$ , weight $k$ , and Atkin-Lehner sign pattern $σ$ , and $S_{k}^{new, σ}$ denote its new subspace. In this paper, we stu…

Interlacing for zeros of the Serre derivative of Eisenstein series

Maggie Bohanek, Owen McGinty, Erick Ross +2

In 1970, Rankin and Swinnerton-Dyer showed that the non-elliptic zeros of Eisenstein series $E_{k}$ in the fundamental domain all lie on the lower arc $\{ e^{iθ}: \fracπ{2} < θ< \fra…

Equidistribution of CM points and RM curves

Erick Ross, Hui Xue

In 1988, William Duke showed that CM points of fundamental discriminant $D$ are equidistributed in the complex upper half-plane $H$ as $D \to - \infty$ . He also showed a si…

Boundary CM points and class groups of small exponent

David Aiken, Erick Ross, Dmitriy Shvydkoy +1

Let $F$ denote the fundamental domain for $SL_{2} (Z)$ on the upper half plane $H$ . William Duke showed that as fundamental discriminants $D \to -\in…

Proportion of Atkin-Lehner sign patterns and Hecke Eigenvalue Equidistribution

Erick Ross, Alexandre van Lidth, Martha Rose Wolf +1

Let $N \geq 1$ , $k \geq 2$ even, and $σ$ denote a sign pattern for $N$ . In this paper, we first determine the exact proportion of forms in $S_{k} (N)$ and $S_{k}^{new} (N)$ with a g…

Hecke Eigenvalue Equidistribution over the Newspaces with Nebentypus

Erick Ross

Fix a prime $p$ , and let $T_{p}^{new} (N, k, χ) := χ (p)^{- 1/2} p^{- (k - 1) /2} T_{p}^{new} (N, k, χ)$ denote the normalized $p$ 'th Hecke operator over the newspace wi…

Dimension sequences of modular forms

Erick Ross

For $N \geq 1$ , let $S_{2}^{new} (N)$ denote the newspace of cuspidal modular forms of weight $2$ and level $N$ . In 2004, Greg Martin conjectured that as a sequence in $N$ , $…

Asymptotics and sign patterns of Hecke polynomial coefficients

Erick Ross, Hui Xue

We determine the asymptotic behavior of the coefficients of Hecke polynomials. In particular, this allows us to determine signs of these coefficients when the level or the weight i…

Zeros of even and odd period polynomials

Grace Ko, Jennifer Mackenzie, Erick Ross +1

Let $f \in S_{k} (Γ_{0} (N))$ be a newform, and let $r_{f}^{\pm} (X)$ denote its corresponding even and odd period polynomials. For sufficiently large level and weight, we show that the zer…

Let $T_{m} (N, k, χ)$ be the $m$ -th Hecke operator of level $N$ , weight $k \geq 2$ , and nebentypus $χ$ , where $N$ is coprime to $m$ . We first show that for any given $m \geq 1$ , the sec…

We determine the average size of the eigenvalues of the Hecke operators acting on the cuspidal modular forms space $S_{k} (Γ_{0} (N))$ in both the vertical and the horizontal perspective…

Consider $N \geq 1$ , $k \geq 2$ , and $χ$ a Dirichlet character modulo $N$ such that $χ (- 1) = (- 1)^{k}$ . For any bound $B$ , one can show that $dim S_{k} (Γ_{0} (N), χ) \leq B$ for only finit…
