WebA Finsler space is said to be geodesically reversible if each oriented geodesic can be reparametrized as a geodesic with the reverse orientation. A reversible Finsler space is geodesically reversible, but the converse need not be true. In this note, building on recent work of LeBrun and Mason, it is shown that a geodesically reversible Finsler metric of … Webclause of the LeBrun construction. In fact, Pedersen observes that the principal symmetry of the Berger sphere induces a Killing field on Mand applies the Jones and Tod construction [7] to show that the Einstein metric on Mis given locally by the total space of an abelian monopole over the round metric on S3. It is then not

It is shown that M has an either complex or almost Kaehler twistor space iff it has a flat symplectic connection.
