An infinitesimal variant of Guo-Jacquet trace formula I: the case of
arXiv:1904.07102
Abstract
We establish an infinitesimal variant of Guo-Jacquet trace formula for the case of . It is a kind of Poisson summation formula obtained by an analogue of Arthur's truncation process. It consists in the equality of the sums of two types of distributions which are non-equivariant in general: one type is associated to rational points in the categorical quotient, while the other type is the Fourier transform of the first type. For regular semi-simple points in the categorical quotient, we obtain weighted orbital integrals.
