Arithmetic Siegel-Weil formula on : singular terms

Baiqing Zhu

For arbitrary level , we relate the generating series of codimension 2 special cycles on to the derivatives of a genus 2 Eisenstein series, especially the s…

The regularity of difference divisors

Baiqing Zhu

For a prime number , we explain the construction of the difference divisors on the unitary Rapoport-Zink spaces of hyperspecial level and the GSpin Rapoport-Zink spaces of hyp…

Arithmetic Siegel-Weil formula on

Baiqing Zhu

We establish the arithmetic Siegel-Weil formula on the modular curve for arbitrary level , i.e., we relate the arithmetic degrees of special cycles on $\mat…
