Abstract
This paper is a study of the relationship
between two constructions associated with Cartan geometries, both of
which involve Lie algebroids: the Cartan algebroid, due to
[Blaom A.D., Trans. Amer. Math. Soc. 358 (2006), 3651–3671], and tractor calculus [Cap A., Gover A.R., Trans. Amer. Math. Soc. 354 (2001), 1511–1548].
Key words:
adjoint tractor bundle; algebroid connection; algebroid representation; Cartan connection; Cartan geometry; Lie algebroid; tractor calculus.
