摘要: Let X be a complex surface admitting a nowhere vanishing holomorphic 2-form; such a form induces a holomorphic symplectic structure on X. In this talk, we consider the case when X is an elliptic surface and study how the symplectic geometry is related to the underlying complex geometry of the elliptic fibration. Applications will be addressed to the classifications of isogenies of symplectic elliptic surfaces. 

The talk is based on a joint work with Jun-Muk Hwang.
