Contributions in Differential Geometry

The conference is dedicated to the 65th birthday and retirement of Lionel Bérard Bergery, professor at the university of Nancy.

The topic, Differential Geometry, should be intended in a broad sense, encompassing also connections with other fields of Mathematics and General Relativity.

How to reach the Campus Limpertsberg

Travel

By plane

The Luxembourg airport is connected by regular flights to all main destinations.

A regular bus service, operated by Flibco, connects the train station to the Frankfurt-Hahn airport, which is served by low-cost flights to many European destinations.

By train

See the websites of the Luxembourg rail company CFL, or SNCF, or Deutsche Bahn.

Accomodation

A list of hotels in Luxembourg is available here. There is also a youth hostel.

Registration & fee
