# Where did (or will) appear: “Funktorialität in der Theorie der automorphen Formen” by Langlands?

In 2010 Langlands wrote an article with the title Funktorialität in der Theorie der automorphen Formen: Ihre Entdeckung und ihre Ziele. On the IAS website, he says that

This note ... was written as commentary to accompany the original letter in a collection of documents on reciprocity laws and algebraic number theory, ... to appear.

By the original letter he means of course his famous Letter to André Weil in which the Langlands conjectures were first formulated.

Questions. Has this collection of documents already appeared? If not, when and where is it likely to appear? What other documents does it contain?

Would you please be kind enough to translate the title for non German speakers? – Sylvain JULIEN Jul 6 '12 at 17:22

Thank you but actually I understood this part. What I don't understand are the words "Entdeckung" and "Ziele". – Sylvain JULIEN Jul 6 '12 at 22:40
Entdeckung = discovery, découverte ; Ziele = aims, objectifs. – Chandan Singh Dalawat Jul 7 '12 at 1:39
Ok, thank you very much. – Sylvain JULIEN Jul 7 '12 at 11:31
