(Contributed by BJ, 6-Jul-2021.) (Proof shortened by Wolf Lammen, 11-Oct-2021.) |
Theorem | axc11rv 2139* | Version of axc11r 2187 with a disjoint variable condition on and , which is provable, on top of { ax-1 6-- ax-7 1935 }, from ax12v 2048 (contrary to axc11 2314 which seems to require the full ax-12 2047).

Theorem | sb56 2150* | Two equivalent ways of expressing the proper substitution of for in , when and are distinct. Theorem 6.2 of [Quine] p. 40. The proof does not involve df-sb 1881. The implication "to the left" is equs4 2290 and does not require any dv condition (but the version with a dv condition, equs4v 1930, requires fewer axioms). Theorem equs45f 2350 replaces the dv condition with a non-freeness hypothesis and equs5 2351 replaces it with a distinctor as antecedent. (Contributed by NM, 14-Apr-2008.) Revised to use equsexv 2109 in place of equsex 2292 in order to remove dependency on ax-13 2246. (Revised by BJ, 20-Dec-2020.) |

Theorem | cleljustALT 2185* | Alternate proof of cleljust 1998.
