Geodesic Equations on Diffeomorphism Groups
Cornelia Vizman Department of Mathematics, West University of Timişoara, Romania
Abstract:
We bring together those systems of hydrodynamical type that can be written as geodesic equations on diffeomorphism groups or on extensions of diffeomorphism groups with right invariant $L^2$ or $H^1$ metrics. We present their formal derivation starting from Euler's equation, the first order equation satisfied by the right logarithmic derivative of a geodesic in Lie groups with right invariant metrics.
Keywords:
Euler's equation; diffeomorphism group; group extension; geodesic equation.
