Title: Parabolic geometry of a car
Abstract: I show that a car, viewed as a nonholonomic system, provides an
example of a flat parabolic geometry of type (SO(2, 3), P12), where P12 is
a Borel parabolic subgroup in SO(2, 3). I discuss the relations of this
geometry of a car with the geometry of circles in the plane (a low
dimensional Lie sphere geometry), the geometry of 3-dimensional conformal
Minkowski spacetime, the geometry of 3-rd order ODEs, projective contact
geometry in three dimensions, and the corresponding twistor fibrations.
I hope that the time permits to talk about all of these topics.
