Speculations on cubic surfaces: Hodge and Galois theory |
Abstract |
I will discuss work in progress with Domingo Toledo. (a) What can one say about the locus of cubic surfaces with periods certain number fields? (Periods to defined: not what you might think they are). (b) What can one say about their Galois representations? The main object of study is a certain natural l-adic representation whose image we hope to prove is large. |
