*„Right-invariant metrics on the diffeomorphism group“*

/Abstract:/

/The interest in right invariant metrics on the diffeomorphism group is 
fueled by its relations to hydrodynamics. Arnold noted in 1966 that 
Euler's equations, which govern the motion of ideal, incompressible 
fluids, can be interpreted as geodesic equations on the group of volume/

/preserving diffeomorphisms with respect to a suitable Riemannian 
metric. Since then other PDEs arising in physics have been interpreted 
as geodesic equations on the diffeomorphism group or related 
spaces.Examples include Burgers' equation, the KdV and Camassa-Holm 
equations or the Hunter-Saxton equation.Another important motivation for 
the study of the diffeomorphism group can be found in its appearance in 
the field of computational anatomy and image matching: the space of 
medical images is acted upon by the diffeomorphism group and differences 
between images are encoded by diffeomorphisms in the spirit of 
Grenander's pattern theory. The study of anatomical shapes can be thus 
reduced to the study of the diffeomorphism group.Using these 
observations as a starting point, I will consider the class of Sobolev 
type metrics on the diffeomorphism group of a generalmanifold M. I will 
discuss the local and global well-posedness of the corresponding 
geodesic equation, study the induced geodesic distance and present 
selected numerical examples of minimizing geodesics./*//*
