Hyperbolic analogue of the Bezdek–Connelly–Kertész average-degree conjecture
Let be a packing of disks of radius in the hyperbolic plane , and let denote the average degree of its contact graph. Hyperbolic average-degree conjecture. For arbitrary such packings,
This is the still-open hyperbolic counterpart of the corresponding spherical result, which is known.
