Geometric structures modeled on affine hypersurfaces and generalizations of the Einstein Weyl and affine hypersphere equations.
[arXiv:0909.1897]  Projectively invariant star products. International Mathematics Research Papers 9 (2005), 461510, 2005. [math.DG:0504596]. (An [erratum] clarifies some ambiguities in the exposition.)
 Contact projective structures. Indiana University Mathematics Journal 54 (2005), 1547–1598. [math.DG:0402332]. (Note: In the statement of Theorem B, the assumption that the ambient connection is homogeneous is omitted, although it is assumed in the proof, and is necessary for the uniqueness.)
 Contact Schwarzian derivatives. Nagoya Mathematical Journal 179 (2005), 163187. [math.DG:0405369]
 Contact path geometries. [math.DG:0508343] (I intend someday to rewrite this article completely. The arXiv version contains some mostly inconsequential but potentially confusing misstatements.)
