Modified Bloch–Beilinson prediction via the niveau filtration

About 9 years old · traced to

Let XX be an abelian variety of dimension dd over C\mathbf{C}, let N~1Hd(X)\widetilde{N}^1H^d(X) be the first niveau-filtration step, and let GdCH0(X)G^dCH_0(X) be the deepest piece of the divisor-intersection filtration. Suppose f:X→Xf:X\to X is an automorphism such that the induced map

f∗:Hd(X)N~1Hd(X)→Hd(X)N~1Hd(X)f_*:\frac{H^d(X)}{\widetilde{N}^1H^d(X)}\to\frac{H^d(X)}{\widetilde{N}^1H^d(X)}

is the identity. Modified Bloch–Beilinson prediction. The restriction of f∗:CH0(X)→CH0(X)f_*:CH_0(X)\to CH_0(X) induces the identity

f∗:GdCH0(X)→GdCH0(X).f_*:G^dCH_0(X)\to G^dCH_0(X).

The modification replaces the top holomorphic-form quotient by the quotient through the niveau filtration; its validity is open in the stated generality.
