The theorems, unconditionally #
The theorems of record, carrying no hypothesis: Deligne's theorem,
in fibre-functor form, is RS.deligne_theorem
(RS/Classical/Deligne/DeligneAssembly.lean),
so the forms in RS/TheoremForward.lean, RS/TheoremQuant.lean,
RS/TheoremTotal.lean, RS/TheoremDimension.lean,
RS/TheoremPadding.lean and RS/TheoremConverse.lean that take it as
an argument are applied to
it here. Those forms remain available alongside: they exhibit the
dependency structure, which is what a reader checking the argument
against the literature wants.
The envelope's semisimplicity and abelianness come from the
factorial trace obstruction. Assembly/BlueprintFactorial checks
that the forward summits use this theorem and exclude the appendix
nilpotent-trace and trace-zeta mechanisms.
The axiom checks are pinned in
RS/Assembly/BlueprintDeligne.lean.
The Regts–Sevenster theorem: every graph parameter with exponentially bounded edge-connection rank is a mixed partition function.
The Regts–Sevenster theorem, quantitative form.
The Regts–Sevenster theorem with at most R colours in total:
the representing functional satisfies k + 2 * ℓ ≤ R.
Every parameter with exponentially bounded connection rank has a model attaining its minimum total colour dimension.
The even connection-rank growth rate is the minimum total number of colours of a representing mixed model.
Prescribed parity dimensions are characterized by the total rank bound and the free-circle value.
The characterisation: for a normalised isomorphism-invariant parameter, bounded edge-connection rank and being a mixed partition function are equivalent.
The quantitative round trip.
