Langlands' comments:
Although I have the feeling of having left unfinished almost every
mathematical project undertaken, the study of endoscopy and
the stabilized trace formula was, in this respect, one of the most
unsatisfactory of all. It went on for a very long time
without reaching
any very cogent conclusions. This now seems with hindsight to
have been inevitable. The efforts of
a number of excellent mathematicians make it
clear that the problems to be solved,
many of which
remain outstanding, were much more difficult
than I appreciated. In particular, the fundamental lemma
which is introduced in these notes,
is a precise and purely combinatorial statement that I thought
must therefore of necessity yield to a straightforward analysis.
This has turned out differently than I foresaw.
Without the kind invitation of MarieFrance
Vignéras to deliver lectures at the École
normale supérieure de jeunes filles,
I would never have attempted to communicate the inchoate
results at my disposition and I would have continued,
no doubt unsuccessfully, to struggle with problems,
both local and global,
that were beyond me. The lectures were an occasion to clarify
and organize the few ideas that I had, and have served
as a stimulus to other, more competent, investigators.

The paper
Beyond endoscopy
This paper has appeared in the Shalika volume, published
by the Johns Hopkins Univesity Press. The published paper
is not exactly the same as that here because the
text was modified by the Press, apparently
for reasons of economy. Among other things footnotes were
removed and this required somewhat brutal measures. The
version in this collection is the preferred version.
The paper
Un nouveau point
de repère dans la theorie des forme automorphes
The following paper is quite informal and it may
be some time before I can seriously reflect on the
suggestions it contains. I am grateful to Freydoon
Shahidi for suggesting that as an interim measure I
write the paper for submission to the Canadian Mathematical
Bulletin whose editors have, I believe, accepted it.
