Abstract
In this paper, we proved a local arithmetic Siegel-Weil formula for a -Shimura variety at a ramified prime, a.k.a. a Kudla-Rapoport conjecture at a ramified case. The formula needs to be modified from the original Kudla-Rapoport conjecture. In the process, we also gives an explicit decomposition of the special divisors of the Rapoport-Zink space of unitary type (Kr\"amer model). A key ingredient is to relate the Rapoport-Zink space to the Drinfeld upper plane.
