A car as parabolic geometry
C. Denson Hill, PaweÅ Nurowski
The paper shows that the kinematics of a car, modeled as a nonholonomic system, realize a flat parabolic geometry of type (SO(2,3), P₁₂) and connects this structure to several clas…

Convex programs for minimal-area problems
Matthew Headrick, Barton Zwiebach
The paper formulates the minimal‑area problem for Riemann surfaces—requiring all non‑contractible curves to have length ≥ 2π—as a local convex optimization problem using calibratio…
