Thesis Title Cohomology of elliptic curves
Thesis Abstract The conjecture of Birch and Swinnerton-Dyer relates the arithmetic of elliptic curves defined over a number field to the analytically defined L-function. The arithmetic side involves the rank of the Mordell-Weil group and the order of a cohomologically defined Tate-Shafarevich group. Refinement of this conjecture, like the equivariant Tamagawa number conjecture, study the variation of these under Galois extensions. In certain special situations it is possible to use Kolyvagin's derivative method for constructing Galois cohomology classes even when the Galois group is not abelian.
