Title:  The extent to which length of closed geodesics determines a
strictly convex projective structure

Abstract:  A convex real projective structure on a manifold gives a
(non-Riemannian) metric which in turn assigns a length to every
element of the fundamental group. We show that two distinct structures
assign the same length to every element iff the two structures are
dual, and that a structure is self dual iff it is a hyperbolic
structure. This result was also (mostly) proved by Inkang Kim.
