How statement and proof provenance work

The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.

  • Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
  • AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
  • AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.

These labels describe origin, not correctness: citations and verification chips remain separate evidence.

The additive and multiplicative real Lie groups

Example

Assume ACω. The groups (R,+), (R>0,⋅), and (R×,⋅) are one-dimensional real Lie groups. Their exponentials are respectively

exp⁡(R,+)(x)=x,exp⁡(R>0,⋅)(x)=ex,exp⁡R×(x)=ex.

The last map lands in the positive identity component.

Facts & Assumptions

Given: The displayed groups with their open-submanifold structures.

[F1]

Smooth group operations define a Lie group. Lie group.

[F2]

The Lie-group exponential is the time-one value of the invariant integral curve. Exponential map of a Lie group.

[F4]

The exponential-map interface [F2] assumes countable choice and records its use through the supplied invariant-field and completeness result. The Axiom of Countable Choice (ACω).

Verification

1.1F1algebra

Addition and negation are smooth on R; multiplication and inversion a↦1/a are smooth on each of the open sets R>0 and R×. Hence [F1] gives the three one-dimensional Lie groups.

2.1F2F3step 1.1

The curve t↦tx is the additive one-parameter subgroup with derivative x at zero. The curve t↦etx is a multiplicative one-parameter subgroup by [F3], has derivative x at zero, and stays positive. By [F2] their time-one values give the displayed formulas.

All groups are nonempty and one-dimensional; R× is disconnected but the other two are connected. At x=0 all exponentials give the identity. No metric, degeneracy, endpoint issue, or biconditional occurs. The assumed ACω is used by [F2] through its stated supplier chain, with no further choice.

Dependency tree · two levels

25 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
