The basis functions of Fourier interpolation

David Berghaus, Andriy Bondarenko, Danylo Radchenko +2

The basis functions of the Fourier interpolation formula of Radchenko and Viazovska, constructed by means of weakly holomorphic modular forms for the Hecke theta group, are entire…

Fourier interpolation in dimensions 3 and 4 and real-variable Kloosterman sums

Danylo Radchenko, Qihang Sun

We give a construction of radial Fourier interpolation formulas in dimensions 3 and 4 using Maass--Poincaré type series. As a corollary we obtain explicit formulas for the basis fu…

Vanishing properties of Kloosterman sums and Dyson's conjectures

Qihang Sun

In a previous paper arXiv:2406.06294 [math.NT], the author proved the exact formulae for ranks of partitions modulo each prime . In this paper, for and , we prove…

Exact formulae for ranks of partitions

Qihang Sun

In 2009, Bringmann arXiv:0708.0691 [math.NT] used the circle method to prove an asymptotic formula for the Fourier coefficients of rank generating functions. In this paper, we prov…

Uniform bounds for Kloosterman sums of half-integral weight, same-sign case

Qihang Sun

In the previous paper [Sun23], the author proved a uniform bound for sums of half-integral weight Kloosterman sums. This bound was applied to prove an exact formula for partitions…

Effective estimates for traces of singular moduli

Oscar E. González, Qihang Sun

Traces of singular moduli can be approximated by exponential sums of quadratic irrationals. Recently Andersen and Duke used theory of Maass forms to estimate generalized twisted tr…

Uniform bounds for Kloosterman sums of half-integral weight with applications

Qihang Sun

Sums of Kloosterman sums have deep connections with the theory of modular forms, and their estimation has many important consequences. Kuznetsov used his famous trace formula and g…
