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 ${A C}_{ω}$ . The groups $(R, +)$ , $(R_{> 0}, \cdot)$ , and $(R^{\times}, \cdot)$ are one-dimensional real Lie groups. Their exponentials are respectively

$\exp_{(R, +)} (x) = x, \exp_{(R_{> 0}, \cdot)} (x) = e^{x}, \exp_{R^{\times}} (x) = e^{x} .$

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.

[F3]

The ordinary exponential satisfies $e^{s + t} = e^{s} e^{t}$ and has derivative $e^{t}$ . The exponential addition formula $\exp (x + y) = \exp (x) \exp (y)$ . The exponential function is smooth and $(\exp)^{'} = \exp$ .

[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 ( ${A C}_{ω}$ ).

Verification

technique · direct

1.1

Addition and negation are smooth on $R$ ; multiplication and inversion $a \mapsto 1 / a$ are smooth on each of the open sets $R_{> 0}$ and $R^{\times}$ . Hence [F1] gives the three one-dimensional Lie groups.

F1algebra

2.1

The curve $t \mapsto t x$ is the additive one-parameter subgroup with derivative $x$ at zero. The curve $t \mapsto e^{t x}$ 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.

3.1

All groups are nonempty and one-dimensional; $R^{\times}$ 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 ${A C}_{ω}$ is used by [F2] through its stated supplier chain, with no further choice.
