An adelic approach to the Kudla-Millson lifts over totally real number fields

Yingkun Li, Mingkuan Zhang, Riccardo Zuffetti

We compute the Fourier expansions of the Kudla-Millson theta lifts of vector-valued Hilbert cusp forms of parallel weight. These expansions are with respect to 0-dimensional cusps…

The Siegel-Weil formula in geometry and arithmetic

Jan Hendrik Bruinier, Riccardo Zuffetti

The present paper is an extended version of the lecture notes of a course given by the first author at the summer school on Formulas of Siegel and Weil (Bielefeld, September 2025).…

Lefschetz decompositions of Kudla-Millson theta functions

Jan Hendrik Bruinier, Riccardo Zuffetti

In the 1980's Kudla and Millson introduced a theta function in two variables. It behaves as a Siegel modular form with respect to the first variable, and is a closed differential f…

Injectivity of the genus 1 Kudla-Millson lift on locally symmetric spaces

Ingmar Metzler, Riccardo Zuffetti

Let be an even indefinite lattice. We show that if splits off a hyperbolic plane and a scaled hyperbolic plane, then the Kudla-Millson lift of genus associated to i…

The Kudla-Millson lift of Siegel cusp forms

Paul Kiefer, Riccardo Zuffetti

We study the injectivity of the Kudla-Millson lift of genus 2 Siegel cusp forms, vector-valued with respect to the Weil representation associated to an even lattice L. We prove tha…

Unfolding and injectivity of the Kudla-Millson lift of genus 1

Riccardo Zuffetti

We unfold the theta integrals defining the Kudla-Millson lift of genus 1 associated to even lattices of signature (b,2), where b>2. This enables us to compute the Fourier expansion…
