Pink–Zilber conjecture for curves in semiabelian schemes
Pink–Zilber conjecture for curves in semiabelian schemes
Let be a semiabelian scheme over a variety defined over , and let be a curve which is not contained in any proper algebraic subgroup of . Define
where is the union of all algebraic subgroups of the fibre of codimension at least .
Pink–Zilber conjecture. The intersection is finite.
This is a special case of the Pink–Zilber unlikely-intersections conjecture, extending Manin–Mumford-type statements to families of algebraic subgroups in semiabelian varieties. Its status is not specified in the source.
