Tate shafarevich group
WebTheorem 1.1. Let E=Q be an elliptic curve whose Tate-Shafarevich group X(E=Q) has nite p-primary part. Suppose that the p-adic height on the ne Selmer group is non-degenerate. Then there is an injection with nite cokernel J of R(E=Q) into the cokernel of the corestriction map cor: lim pn n H1(G ( Q);TpE) ˜H1(G (Q);T E): WebNow we can define the Selmer group and the Tate-Shafarevich group. Definition 1.1 (Selmer group). The Selmer group, denoted S(n)(E=K) is defined by S(n)(E=K) = ker H1(G K;E[n]) ! Y v H1(G K v;E)!: 2. Mordell-Weil Definition1.2 (Tate-Shafarevichgroup).

A p p-fusion system on S S is a category whose objects are the subgroups of S and whose morphisms are certain injective group homomorphisms. Fusion systems are of interest in modular representation theory, algebraic topology, and local finite group theory.
