| Abstract: Daniel Bertrand recently found an example of a groupscheme J over a complex curve S and a section P with the following properties. The fibres of J over S are extension of an elliptic curve by the multiplicative group: J is semi-abelian, of toric rank one. The union of the n.P(S), over n in the integers, is dense in J. There exists an infinite set of s in S such that P(s) is torsion. I will present this example from the point of view of generalised jacobians. And I will show, still following Bertrand, why this counter-example to the naive version of the relative semi-abelian Manin-Mumford conjecture is actually an example of Richard Pink's common generalisation of the conjectures of Andre-Oort, Manin-Mumford, and Mordell-Lang. arXiv |
