SYMPLECTIC GEOMETRY AND HILBERT'S FOURTH J.C. ALVAREZ PAIVA
 

Summary: SYMPLECTIC GEOMETRY AND HILBERT'S FOURTH
PROBLEM
J.C. ´ALVAREZ PAIVA
Abstract. Inspired by Hofer's definition of a metric on the space of
compactly supported Hamiltonian maps on a symplectic manifold, this
paper exhibits an area-length duality between a class of metric spaces
and a class of symplectic manifolds. Using this duality, it is shown that
there is a twistor-like correspondence between Finsler metrics on RPn
whose geodesics are projective lines and a class of symplectic forms on
the Grassmannian of 2-planes in Rn+1
