How to get to Göttingen
The easiest way to get from Frankfurt airport to Göttingen is via the high-speed train ICE.
A timetable [PDF] covering this route for the time of the conference is available for download.
Take care: there are two train stations at Frankfurt airport. You have to take the "Fernbahnhof".
Often an ICE ticket is bookable along with an airplane ticket for a discount. Ask for it when ordering your plane ticket.
