The Cotton tensor in the projective geometry of sprays
Abstract:
I define, by analogy with the projective theory of linear connections, a Cotton tensor for any spray, and discuss its role in the projective geometry of sprays.
Keywords: projective geometry of sprays, Berwald connection, Weyl tensor, Cotton tensor, R-flat spray
