| 2025-02-26 11:57:36 +0100 | <Athas> | tomsmeding: I do use Numeric.AD.Double, but what does +ffi do? |
| 2025-02-26 11:57:04 +0100 | <lambdabot> | Consider it noted. |
| 2025-02-26 11:57:04 +0100 | <tomsmeding> | @tell Athas You may get better performance with 'ad' if you use Numeric.AD.Double _and_ enable the +ffi flag |

| 2025-02-26 11:10:40 +0100 | <ames> | it ranges from subtly incorrect and extra verbose to complete and utter bullshit |

| 2025-02-26 11:09:54 +0100 | <ames> | just don't listen to nlab when it comes to type theory |
| 2025-02-26 11:09:10 +0100 | <tomsmeding> | I'd personally expect that as soon as that bouncing has any kind of _property_ (it converges, or you end up where you started, ...) then it _does_ have a name |
| 2025-02-26 11:06:18 +0100 | <cheater> | even smoothly so |
| 2025-02-26 11:06:11 +0100 | <cheater> | and can be continuated |
| 2025-02-26 11:05:47 +0100 | <cheater> | and a topology |
| 2025-02-26 11:05:44 +0100 | <cheater> | it can easily create congruences, for example |
| 2025-02-26 11:04:59 +0100 | <cheater> | anyways i think the idea of being able to bounce back and forth an infinite amount of times is pretty interesting |
| 2025-02-26 11:04:44 +0100 | <cheater> | you don't know about ncatlab? |

| 2025-02-26 10:59:04 +0100 | <Leary> | I'm still not sure what the original statement is supposed to be. f and g are partial functions with opposite co/domains and the property that each is total on the other's range? |
| 2025-02-26 10:58:01 +0100 | <[exa]> | anyway yeah, I'd say the original definiton would need a bit more of a spirit to it to actually spawn a useful name |
| 2025-02-26 10:57:26 +0100 | <[exa]> | ah well okay in math that could cause issues, I see |
| 2025-02-26 10:57:24 +0100 | <tomsmeding> | but if you already have the types of f and g, there's nothing more to specify! |
| 2025-02-26 10:57:10 +0100 | <[exa]> | f.f doesn't type |
| 2025-02-26 10:56:17 +0100 | <tomsmeding> | if it's just "f . g", then it's weaker; if you also include "f . f", then it's stronger |
| 2025-02-26 10:55:59 +0100 | <tomsmeding> | depends on what compositions you mean when you say "compositions of f and g" |
| 2025-02-26 10:55:55 +0100 | <[exa]> | so I'd say it's the same |
| 2025-02-26 10:55:40 +0100 | <[exa]> | the totality of the composition implies exactly the domain-is-a-superset property that was requested, and I just run it in both directions |
| 2025-02-26 10:54:41 +0100 | <tomsmeding> | that's not quite the same statement, is it? |
| 2025-02-26 10:54:37 +0100 | <cheater> | i don't like puzzle definitions |
| 2025-02-26 10:54:20 +0100 | <[exa]> | cheater: you can just say that compositions of f and g are total |
| 2025-02-26 10:52:11 +0100 | <cheater> | that sounds like something out of control theory. |

| 2025-02-26 10:49:13 +0100 | <tomsmeding> | you can call it a "back-and-forth" |
| 2025-02-26 10:48:39 +0100 | <cheater> | if no such thing is described then i shall coin that as a speculative function pair (or tuple for a more complex graph) |

| 2025-02-26 10:46:18 +0100 | <cheater> | no, they have no such property as stated |
| 2025-02-26 10:45:55 +0100 | <cheater> | i think that's interesting enough. |
