Abstract:  

A major achievement in the Langlands program is Arthur's 2013 book on the endoscopic classification of square-integrable automorphic forms of  (quasi-split) classical groups. In the first lecture, I will summarize the main results of this book and some key ingredients of their proofs. In particular, some of the ingredients were at that point in time anticipated but not yet fully written down. Several of these ingredients have subsequently been addressed. In the second lecture, I will discuss a recent work with Hiraku Atobe, Atsushi Ichino, Tasho Kaletha, Alberto Minguez and Sug Woo Shin in which we supply most of the remaining ingredients.
