Horizontal Distribution Relations for Special Cycles on Unitary Shimura Varieties: Split Case

Reda Boumasmoud, Ernest Hunter Brooks, Dimitar Jetchev

We study the local behavior of special cycles on Shimura varieties for $\mathbf{U}(2,1)\times \mathbf{U}(1,1)$ in the setting of the Gan-Gross-Prasad conjectures at primes $\tau$ o…
