1. Much like affine connections, projective connections also define geodesics.
2. Torsion is also useful in the study of unparametrized families of geodesics, via the associated projective connection.
3. An analogous pseudometric was constructed for flat affine and projective structures in and then generalized to ( normal ) projective connections.
4. The structure of a projective connection is modeled on the geometry of projective space, rather than the affine space corresponding to an affine connection.
5. I was going to drop in to mention arbitrary manifolds, but stopped because I didn't know the right words / definitions necessary for projective connection : ) talk ) 18 : 16, 31 May 2012 ( UTC)
6. It's difficult to find projective connection in a sentence. 用projective connection造句挺難的
7. The term " tractor " is a portmanteau of " Tracy Thomas " and " twistor ", the bundle having been introduced first by T . Y . Thomas as an alternative formulation of the Cartan conformal connection, and later rediscovered within the formalism of local twistors and generalized to projective connections by Michael Eastwood " et al . " in
8. The area was much studied by mathematicians from around 1890 for a generation ( by J . G . Darboux, George Henri Halphen, Ernest Julius Wilczynski, E . Bompiani, G . Fubini, Eduard & # 268; ech, amongst others ), without a comprehensive theory of differential invariants emerging . 蒷ie Cartan formulated the idea of a general projective connection, as part of his method of moving frames; abstractly speaking, this is the level of generality at which the Erlangen program can be reconciled with differential geometry, while it also develops the oldest part of the theory ( for the projective line ), namely the Schwarzian derivative, the simplest projective differential invariant.
