On the structure of endoscopic transfer factors

Abstract

There are two versions of endoscopic transfer factors to accommodate the different versions, classical or renormalized, of the local Langlands correspondence. An examination of the structure of these complex-valued factors shows that the versions are related in a simple manner. We gather various consequences and indicate ways in which these are useful for the harmonic analysis associated with endoscopic transfer.
