A family of threefolds with remarkable properties (namely: the unreasonable effectiveness of the Schoens) – Antonella Grassi (Università degli Studi di Bologna)


Department of Mathematics, Aula Magna.


The fiber product of certain rational elliptic surfaces were first studied by Schoen in the 80s to answer questions from string theory. Over the decades  the  “Schoens”  have provided evidence for various conjectures as well as counterexamples to others. I will discuss these conjectures, the unusual features of the Schoens, and present other  open questions.

Further information is available on the event page on the Indico platform.
