The intersection-map conjecture for surfaces with and
The intersection-map conjecture for surfaces with and
Let be a surface with geometric genus and irregularity . Let be the group of homologically trivial divisor classes with rational coefficients, and let be the Albanese kernel with rational coefficients. The intersection map is
Assume that the image of the Albanese map has dimension less than . The intersection-map conjecture. The intersection map is zero.
The preceding argument shows that surjectivity would contradict the induced map on and ; the stronger assertion that the map is zero is stated conjecturally in this setting.
