Let K be a number field and X a smooth N-dimensional projective variety over K. The paper defines a height pairing between the subgroups CH i(X) 0 and \(CH^{N+1-i}(X)\) 0 of the Chow groups of cycles homologous to zero in \(\ell\)-adic cohomology. The definition assumes two conjectures which have been verified in the good reduction case and for cycles algebraically equivalent to zero. The pairing is defined via local pairings.
The final section lists important conjectures and problems concerned with arithmetic matters, generalization of Tate-Néron height, K-theory and algebraic cycles, and Hodge cohomology.
