The formal Group of the dual Abelian Variety
ACL: You've already said everything necessary; I am just linking the references [Tate's classic][1] or [Serre's Seminaire Bourbaki][2] [1]: fhoermann.org/Tate%2520%2520pDivisible%2520Groups.pdf [2]: numdam.org/item?id=SB_19661968__10__73_0

Intuition behind the Tamagawa numbers
@Pacetti: I am wondering if you mean JWS Cassels and not B. Casselman. I think Cassels did prove the isogeny invariance for elliptic curves over number fields, but Tate's results are for abelian varieties.

Intuition behind the Tamagawa numbers
@Pacetti: Tate proved the compatibility of the BSD conjecture under isogeny by proving a global duality theorem for finite Galois modules; the $p$part of this in positive characteristic is much more involved. See either Tate's ICM 1962 talk or Milne's Arithmetic Duality Theorems book freely available at www.jmilne.org. As far as I can tell, Tate's results were all proved in the sixties. I do not know of a reference for the work of Casselman that you mention. It would be good to know so that one can correctly attribute the results. Thanks
