Abstract: | Let E1, E2 be elliptic curves with good reduction over a local field k of residue characteristic p. Let X be the smooth projective model of E1 × E2 over the ring of integers of k. We show that KerCH2(X) CH2 (E1 × E2)) is a finite p-group, by giving a new construction of indecomposable elements of H1
Zar(E1 × E2, K2). As an application we show that the prime to p part of the torsion subgroup of CH2(E1 × E2) is finite. |
