Abstract
Let be an elliptic curve and a finite Galois extension with group G. We write EK for the base change of E and consider the equivariant Tamagawa number conjecture for the pair (h 1(EK )(1),). This conjecture is an equivariant refinement of the Birch and Swinnerton-Dyer conjecture for E/K. For almost all primes l, we derive an explicit formulation of the conjecture that makes it amenable to numerical verifications. We use this to provide convincing numerical evidence in favor of the conjecture.
