Theorem | ax1re 6938 |
1 is a real number. Axiom for real and complex numbers, derived from set
theory. This construction-dependent theorem should not be referenced
directly; instead, use ax-1re 6978.
In the Metamath Proof Explorer, this is not a complex number axiom but is proved from ax-1cn 6977 and the other axioms. It is not known whether we can do so here, but the Metamath Proof Explorer proof (accessed 13-Jan-2020) uses excluded middle. (Contributed by Jim Kingdon, 13-Jan-2020.) (New usage is discouraged.) |

Theorem | axaddcom 6944 |
Addition commutes. Axiom for real and complex numbers, derived from set
theory. This construction-dependent theorem should not be referenced
directly, nor should the proven axiom ax-addcom 6984 be used later.

Theorem | axcaucvg 6974* |
Real number completeness axiom. A Cauchy sequence with a modulus of
convergence converges. This is basically Corollary 11.2.13 of [HoTT],
p. (varies). The HoTT book theorem has a modulus of convergence
(that is, a rate of convergence) specified by (11.2.9) in HoTT whereas
this theorem fixes the rate of convergence to say that all terms after
the nth term must be within ![]() ![]() ![]()
Because we are stating this axiom before we have introduced notations
for This construction-dependent theorem should not be referenced directly; instead, use ax-caucvg 7004. (Contributed by Jim Kingdon, 8-Jul-2021.) (New usage is discouraged.) |
