| Jul 26, 2018 at 22:37 | comment | added | Taras Banakh | @YCor Thank you for the suggestion. I have added an explanation in OP. | |
| Jul 26, 2018 at 22:23 | comment | added | YCor | Actually I started editing the post to fix the typo, then saw it could be a pun with "ball" and asked (possibly somebody else would have corrected). Mentioning explicitly that it's a special spelling would have avoided my question. | |

Added Problem 2

Extended the remark a bit.

| Jul 26, 2018 at 21:29 | comment | added | paul garrett | @TarasBanakh, you may spend as much time explaining that it's not a typo as talking about the math... Conceivably "ball-anced", with hyphen to emphasize that you realize what you're doing? Otherwise you'll waste time... | |
| Jul 26, 2018 at 21:19 | comment | added | Taras Banakh | @RW You are right: the action is ballanced if the orbit of any conjugacy class is a ball. | |
| Jul 26, 2018 at 20:59 | comment | added | Taras Banakh | @YCor The (weird) word "ballanced" is invented as a mix of "ball" and "balanced". This is a working terminology. | |

| Jul 26, 2018 at 20:51 | comment | added | R W | Your balanced sets are just unions of conjugacy classes, and an action is balanced if any orbit of any conjugacy class is a ball - right? | |
| Jul 26, 2018 at 20:43 | comment | added | YCor | Is the weird word "ballanced" (with 2 L) invented on purpose? | |
