Borcherds Products for U(1,1)

open access: yes, 2013
The Borcherds lift for indefinite unitary groups, previously constructed by the author, is examined here in greater detail for the special case of the group U(1,1).

Basis for the space of weakly holomorphic modular forms in higher level cases

open access: yesJournal of Number Theory, 2013
Abstract Let k be an even integer. We find a canonical basis for the space of weakly holomorphic modular forms of weight k for Γ 0 + ( p ) and investigate its properties.

Limit of geometric quantizations on Kähler manifolds with T‐symmetry

open access: yesProceedings of the London Mathematical Society, Volume 129, Issue 4, October 2024.
Abstract A compact Kähler manifold M,ω,J$\left(M,\omega,J\right)$ with T$T$‐symmetry admits a natural mixed polarization Pmix$\mathcal {P}_{\mathrm{mix}}$ whose real directions come from the T$T$‐action. In Leung and Wang [Adv. Math. 450 (2024), 109756], we constructed a one‐parameter family of Kähler structures ω,Jt$\left(\omega,J_{t}\right)$’s with ...

The arithmetic of modular grids

open access: yes, 2021
A modular grid is a pair of sequences $(f_m)_m$ and $(g_n)_n$ of weakly holomorphic modular forms such that for almost all $m$ and $n$, the coefficient of $q^n$ in $f_m$ is the negative of the coefficient of $q^m$ in $g_n$. Zagier proved this coefficient

Cohomological connectivity of perturbations of map‐germs

Abstract Let f:(Cn,S)→(Cp,0)$f: (\mathbb {C}^n,S)\rightarrow (\mathbb {C}^p,0)$ be a finite map‐germ with n

Borcherds Forms and Generalizations of Singular Moduli [PDF]

open access: yes, 2005
We give a factorization of averages of Borcherds forms over CM points associated to a quadratic form of signature (n,2). As a consequence of this result, we are able to state a theorem like that of Gross and Zagier about which primes can occur in this ...
