# A generalisation of the Birch and Swinnerton-Dyer conjecture

We know that the grand Riemann hypothesis is a generalisation of the Riemann hypothesis and Generalized Riemann hypothesis. My question is about the existence of a similar generalisation of the Birch and Swinnerton-Dyer conjecture.

The equivariant Tamagawa number conjecture generalizes the BSD conjecture. I am not sure if this is the most general conjecture available.

@ Marc Palm: Does there is a set of special L-functions where this conjecture apply just like the case of the Generalized Riemann hypothesis. – China-Hong Kong Apr 18 '13 at 16:18
Yes this class of functions are called motivic L-functions. Following Scholl you can attach a motive to the new form so those L-functions are motivic. Examples include Artin L-function and Hasse-Weil L-functions. – Arijit Apr 18 '13 at 16:40
@ Arijit: Thank you very much for clarification. – China-Hong Kong Apr 18 '13 at 16:46

The Bloch-Kato and Beilinson's conjectures. Here is an extremely pleasant write up on that http://www.claymath.org/programs/summer_school/2009/BellaicheNotes.pdf http://www.math.jussieu.fr/~nekovar/pu/mot.pdf http://wwwmath.uni-muenster.de/u/peter.schneider/publ/pap/beilin.ps

I believe this is more special then the equivariant Tamagawa conjecture? – Marc Palm Apr 18 '13 at 16:10
Yes you are absolutely right. The equivariant version is of course general than TMC. – Arijit Apr 18 '13 at 16:17

A proof of ETNC => BSD can be found here: Guido Kings http://www.uni-regensburg.de/Fakultaeten/nat_Fak_I/preprints/Preprints2009/26-2009.pdf

For a generalisation of the BSD conjecture in positive characteristic to higher dimensional bases (over finite fields) see http://arxiv.org/abs/1410.5293 and http://arxiv.org/abs/1410.5294
