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.

FALSE: x,y=ixiyi makes F2n an inner product space

Statement

False claim: the standard form on F2n is an inner product.

Facts & Assumptions

Given: the vector x=(1,1)F22.

[L1]

Over F2, one has x,x=ixi (The standard bilinear form x,y=i<nxiyi on Fn).

Refutation

technique · direct
1.1

The vector x=(1,1) is nonzero, but [L1] gives x,x=1+1=0 in F2.

L1given
2.1

An inner product cannot vanish on a nonzero vector, so the false claim fails.

step 1.1

Remarks

  • What remains true is that the form is symmetric and bilinear. That is all the page ever uses over F2.

Dependency tree · two levels

19 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.
