SUMMARY:Bo-Hae Im\, A Hyperelliptic Curve Mapping to Specified Elliptic Curves
DESCRIPTION:     Speaker\n\n\nBo-Hae Im\nKAIST\n\n\n\n\n\n\n(This is a part of Arithemetic Geometry Day in IBS-CCG.) \nWe are interested in the existence and non-existence of rational curves on certain Kummer varieties which can be applied to the rank problem of quadratic twists of elliptic curves. In this talk\, we prove that if the j-invariants of a 21-tuple of elliptic curves E1\, …\, E21 over C are algebraically independent over Q\, there is no hyperelliptic curve which admits a non-trivial morphism to each of the Ei\, which shows the non-existence of rational curves of the Kummer variety of the products of more than 20 elliptic curves.\nThis is a joint work with Michael Larsen and Sailun Zhan.
