A generalization of a theorem of Rankin and Swinnerton-Dyer on zeros of modular forms

Jayce Getz

Rankin and Swinnerton-Dyer (1970) prove that all zeros of the Eisenstein series E k in the standard fundamental domain for Γ lie on A:= {e iθ : π/2 ≤ θ ≤ 2π/3). In this paper we generalize their theorem, providing conditions under which the zeros of other modular forms lie only on the arc A. Using this result we prove a speculation of Ono, namely that the zeros of the unique gap function in M k , the modular form with the maximal number of consecutive zero coefficients in its q-expansion following the constant 1, has zeros only on A. In addition, we show that the j-invariant maps these zeros to totally real algebraic integers of degree bounded by a simple function of weight k.

Partition identities and a theorem of Zagier

Jayce Getz; Karl Mahlburg

In the study of partition theory and q-series, identities that relate series to infinite products are of great interest (such as the famous Rogers-Ramanujan identities). Using a recent result of Zagier, we obtain an infinite family of such identities that is indexed by the positive integers. For example, if m = 1, then we obtain the classical Eisenstein series identity Σλ≥1 odd (-1)(λ-1)/2qλ/(1-q2λ)=q Πn=1∞ (1-q8n)4/(1-q4n)2 If m = 2 and (·/3;) denotes the usual Legendre symbol modulo 3, then we obtain Σλ ≥1 (λ/3) qλ/(1-q2λ=q Πn=1∞ (1-qn)(1-q6n)6/(1-q2n)2(1-q3n)3 We describe some of the partition theoretic consequences of these identities. In particular, we find simple formulas that solve the well-known problem of counting the number of representations of an integer as a sum of an arbitrary number of triangular numbers.

A general simple relative trace formula

Jayce Getz; Heekyoung Hahn

In this paper we prove a relative trace formula for all pairs of connected algebraic groups H G G, with G a reductive group and H the direct product of a reductive group and a unipotent group, given that the test function satisfies simplifying hypotheses. As an application, we prove a relative analogue of the Weyl law, giving an asymptotic formula for the number of eigenfunctions of the Laplacian on a locally symmetric space associated to G weighted by their L 2 -restriction norm over a locally symmetric subspace associated to H0 G.
