Sources consulted: Clay Mathematics Institute Millennium Problems, Wolfram MathWorld, arXiv survey literature, and standard mathematical references.
Summary
- Total problem records: 68
- Unsolved problems surveyed: 67
- Solved boundary markers: 1
- Alignment clusters: 10
RRC axis schema
Projections use the 16-axis RRC manifold vector from 6-Documentation/docs/rainbow_raccoon_compiler_integration.md, restricted here to the most relevant axes:
semantic_entropygeometric_masscompression_pressuretopology_torsionresidual_riskproof_readinessscale_band_declarednegative_control_strengthprojection_declaredshape_closure
Axis values are dimensionless scores in [0,1] (Q0_16-compatible normalized units). Higher values indicate stronger presence of that axis.
RRC shape vocabulary
Shape classes are taken from 4-Infrastructure/shim/rrc_ray_tagger.py and 6-Documentation/docs/rainbow_raccoon_compiler_integration.md:

Notable interconnection patterns
- Zeta/L-function cluster is the densest mathematical hub: RH, GRH, BSD, and the arithmetic implications of EH form a high-weight subnetwork.
- P vs NP is the dominant complexity hub, with reductions to derandomization, fine-grained hardness, hardness of approximation, and algebraic barriers.
- Navier-Stokes / turbulence / Yang-Mills form a PDE-singularity cluster where regularity questions and constructive QFT share regularity DNA.
- Smooth 4D Poincaré / generalized Poincaré are tightly coupled and isolated from the number-theory clusters except through Langlands/motives.
- Cosmology and dark sectors are the most underspecified region: weak
projection_declared, weakscale_band_declared, and highresidual_risk. - Logic/foundations (CH, ZFC consistency) sits at the meta-limit: high
semantic_entropyandresidual_risk, near-zeroproof_readiness.
