Title: Langlands lift from G_2 to PGSp(6)

Abstract: Langlands functoriality is a general principle that predicts correspondences of representations between different groups. The trace formula is a tool to establish such correspondences in (so called) endoscopic cases. The lift from G_2 to PGSp(6) is an example of a non-endoscopic lifting. In this lecture we shall explain how this lifting can be obtained as a dual pair correspondence arising from the minimal representation of E_7.
