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.

Quotient module $M / N$ with scalar multiplication on additive cosets

Definition

Let $N \leq M$ be a submodule of a left $R$ -module. Since the additive group of $M$ is abelian, $N$ is normal, so the additive quotient group $M / N$ consists of the cosets $m + N$ . Its proposed scalar action is

$r (m + N) : = r m + N .$

The well-definedness and module laws are established in The quotient action is well defined and makes $M / N$ a module ↗. The resulting module is the quotient module $M / N$ .
