AMS Summer Institute in Algebraic Geometry is underway in Seattle. It’s a mammoth three-week conference on algebraic geometry. The first week is dedicated to the unlikely connections that have emerged between algebraic geometry and string theory.

Are these ‘unlikely connections’ old things from decades ago or very recent stuff? String Theory has been tightly connected to Algebraic Geometry for as long as I remember. For example the fact that String theory prefers to live in certain dimensions (eg. 26 for bosonic strings) comes straight from the Grothendieck-Riemann-Roch theorem.

It’s new, I think. Aren’t Gromov-Witten invariants fairly new?
