Abstract:

This talk will be about symplectic, rather than complex geometry, but the motivation is from constructions in Kahler geometry. We consider a compact symplectic manifold (X,\omega) and the group G of its symplectomorphisms. We study the action of G on the Frechet space C^\infty(X) of smooth functions, by pullback, and describe properties of convex functions p:C^\infty(X)\to R that are invariant under this action.
