Differential Geometry of the Semi-Geostrophic and Euler Equations
Seminar Room 1, Newton Institute
AbstractThe role of contact and symplectic geometry of the semi-geostophic (SG) equations, in describing their Legendrian and Hamiltonian properties, will be reviewed. Using the geometry of 2-forms in 4 dimensions and the geometry of 3-forms in 6 dimensions, we show that the incompressible Euler equations in 2 and 3 dimensions admit geometric structures akin to the those present in the SG equations.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
