| 2025-04-10 02:31:29 +0200 | <EvanR> | Perhaps it would be more historically accurate to call the operation fregeing, but there are often miscarriages of justice in the appellation of mathematical ideas.) |

| 2025-04-10 19:03:28 +0200 | <ski> | EvanR : doesn't matter. then it's "`f' preserves equality, for all `f'". to be "function application preserves equality", it would have to say that if `f == g' and `a == b', then `f(a) == g(b)' |
| 2025-04-10 19:04:26 +0200 | <ski> | (that (latter) rule itself is often simply called "congruence", btw, taking it for granted that we're talking about function application) |
| 2025-04-10 19:05:04 +0200 | <EvanR> | alright congruence is basically talking about both things together |
| 2025-04-10 19:05:37 +0200 | <ski> | if you want to spell it out, "`==' is a congruence relation wrt function application" |

| 2025-04-10 19:13:33 +0200 | <ski> | a function `f : A -> A' is said to preserve a property `P' on `A', whenever `P(x)' implies `P(f(x))', for all `x' in `A'. `f' is said to reflect the property `P' whenever `P(f(x))' implies `P(x)', for all `x' in `A' |
| 2025-04-10 19:16:09 +0200 | <ski> | if you take `A' to be lambda expressions, and `f' the operation of "lambda-abstracting over the variable `x'", and generalize `P' from a unary relation on `A' to a binary one, specifically the `=' one, then you get "if M = N then \x.M = \x.N" above, from "`f' preserves `P'" |
