Abstract
We study cuspidal automorphic representations of unitary groups of variables with -factor and their central -derivatives by constructing their arithmetic theta liftings, which are Chow cycles of codimension on Shimura varieties of dimension of certain unitary groups. We give a precise conjecture for the arithmetic inner product formula, originated by Kudla, which relates the height pairing of these arithmetic theta liftings and the central -derivatives of certain automorphic representations. We also prove an identity relating the archimedean local height pairing and derivatives of archimedean Whittaker functions of certain Eisenstein series, which we call an arithmetic local Siegel–Weil formula for archimedean places. This provides some evidence toward the conjectural arithmetic inner product formula.
