本文的目的是构造代数圈的高度配对,推广了已知的O-圈和因子的高度配对。设X是定义在数域k上的维数为d的光滑射影簇。对于ps d,令M(X)(resp. AJX))表示余维为p(resp.维数p)在X上定义在k上,在@'(Xk,Q,)中与0共调(分别H2 d-2 p)9取模有理等价。我们将处理#'(X)@ Q,因此不会出现扭转问题,如果我们愿意考虑Xk上的有理等价,我们可能会出现扭转问题。理想情况下,我们希望
The purpose of this paper is to construct height pairings for algebraic cycles, generalizing the known cor:; truction for O-cycles and divisors. Let X be a smooth projective variety of dimension d defined over a number field k. For ps d, let M (X)(resp. AJX)) denote the group of algebraic cycles of codimension p (resp. dimension p) on X defined over k, cohomologous to 0 in@‘(Xk, Q,)(resp. H2d-2p) 9 taken modulo rational equivalence. We will be working with#‘(X)@ Q, so questions of torsion will not arise and we may if we like consider rational equivalence on Xk. Ideally we would want a pairing
