What OpenAI claims

Proves strict positivity of Serre's intersection multiplicity χR(M,N) for nonzero finitely generated modules over any regular local ring, provided M⊗R N has finite length and dim M+dim N=dim R. This resolves the positivity conjecture, including ramified mixed characteristic.

  1. Positivity of Serre's Intersection Multiplicity

    · Preprint, not peer reviewed · PDF

    We prove Serre's positivity conjecture, including ramified mixed characteristic. If two nonzero finitely generated modules over a regular local ring have tensor product of finite length and complementary dimensions, then their intersection multiplicity is strictly positive.

Status

Preprint. The paper has not been independently reviewed. Treat the result as OpenAI's claim until other mathematicians have checked it. If a video exists, it illustrates the statement; it is not the proof.
