FQFT-MICRO-21 — Microscopic Refinement Law

Minimum microscopic refinement datum R and discrete-to-continuum compatibility laws.

Formal Definition

The source FQFT chain states

GqρKMMDHS[Φ;DH],

and describes the graph as being completed into a Hausdorff measure space. What is not currently supplied is the refinement operator that makes that completion mathematical.


MIC-D01 — Minimum Refinement Datum

R25 freezes the minimum microscopic object as

R=((Gn)n1,(n)n1,(dn)n1,(mn)n1,(En)n1,(ιn,n+1)n1),

where:

  1. Gn=(Vn,En) is a finite graph at refinement level n.
  2. n>0 is the mesh scale, with n0.
  3. dn is a metric on Vn.
  4. mn is a positive Borel measure on Vn.
  5. En is a discrete Dirichlet form on L2(Vn,mn).
  6. ιn,n+1:VnVn+1 is an injective nesting or identification map.

A claim of "fractal completion" is undefined until all six components are exhibited.


MIC-P01 — Scale-First Principle

Physics is determined by the scale-indexed system R, not by an unrefined single graph Gq.

No static property of Gq can be promoted to a continuum field-theory property without specifying how it transforms under R.


Discrete-to-Continuum Compatibility Laws

To be admissible, R must satisfy three compatibility criteria:

Metric Compatibility (Gromov–Hausdorff)

(Vn,dn)GH(M,d),

where (M,d) is a compact metric space of finite Hausdorff dimension DH.

Measure Compatibility (Weak Convergence)

ιnmnm,supp(m)=M.

Spectral Compatibility (Mosco / Norm-Resolvent)

The graph Laplacians Ln associated to (En,mn) must converge to a continuum operator Δ on L2(M,m) in the sense of Mosco convergence of Dirichlet forms:

EnME,(Ln+I)1s(Δ+I)1.
