Galois action on L-values

To an elliptic curve E, one can associate various twists L(E,\chi,s) of L-functions. The values of these L-functions at integers
are expected to behave well under the action of a Galois group. In this talk, we will explain how a Galois group acts on some special L-values and indicate some approaches in studying the behaviour under such actions.
