On Finsler Spaces of Douglas Type III

On Locally Dually Flat Finsler Metrics

“…It is well-known that if F = α + β is locally projectively flat, then α is locally projectively flat and β is closed [5]. Actually one can conclude this by (3.2).…”

On the projective geometry of sprays

“…Finsler manifolds with vanishing Douglas tensor were baptized Douglas manifolds by S. Bácsó and M. Matsumoto. Their papers [1]- [3] seem to be promising first steps in attacking the problem.…”
