This conference is to celebrate Tudor Ratiu's 65th birthday with talks
which are in other areas than geometric mechanics. The latter
contributions are discussed in a conference at the CIB 8-11 June
directly preceding the one proposed here.
The aim of the conference is to gather experts in elds of Tudor Ratiu's
wide research interests to honour his research. It is also to honour
Tudor's 17 years at EPFL, as well as his directorship of the CIB for
more than 10 years.
