Abstract:
Jacobian determines a bundle with total space consisting of orientation-preserving diffeomorphisms
of a (connected) manifold over the space of positive functions on this manifold (with integral equal to volume
for a compact manifold). It is proved that, for the $n$-sphere with standard metric, there is a unique
connection on this bundle that is invariant with respect to all isometries of the sphere, and a description of
this connection is given.
Keywords:
group of diffeomorphisms, manifold of constant curvature, connection.
