Abstract

In this article, we relate the fake special cycle classes $z_{\mathbb{L}_{\sigma},r}$ attached to a Hecke eigensheaf $\mathbb{L}_{\sigma}\in\mathrm{Shv}_{\mathrm{Nilp}}(\mathrm{Bun}_G)$ introduced in the author's previous work to the isotypic part of special cycles on Shtukas. As an application, we relate the self-intersection number of the isotypic part of special cycles arising from Rankin--Selberg period to higher derivatives of Rankin--Selberg $L$-functions.
