| Jul 28, 2017 at 11:55 | comment | added | Igor Belegradek | @mmaatthh: you seem to be confused about the definition of a ray. In general, deciding when a geodesic is a ray is nontrivial. A study of rays on certain surfaces of revolution can be found in arxiv.org/abs/1108.1515. | |
| Jul 28, 2017 at 8:02 | comment | added | Misha | Igor's example is correct (with the standard definition of a ray). What definition are you using? | |

| Jul 28, 2017 at 2:04 | comment | added | mmaatthh | @ Igor Belegradek, From any point away from the cap, except one direction(which tangent to the circle), there is a ray starting from any other directions, so your example seems to be not right. | |
