We relate the torsion part of the Abel-Jacobi kernel in the Griffiths group of 1-cycles to a birational invariant analogous to the degree 4 unramified cohomology and an invariant associated to the generalized Hodge conjecture in degree $2{\dim}(X)-3$. We also describe in terms of $\Cal H$-cohomology the Griffiths group of 1-cycles and the group of torsion cycles algebraically equivalent to zero of arbitrary dimension.
Classification : 14C25, 14C15, 14C35
Keywords: 1-cycles, Griffiths group, Abel-Jacobi map, coniveau spectral sequence, $\Cal H$-cohomology, birational invariant
