DIF-FNO: Diffeomorphic Fourier Neural Operator with D'Agnese Barrier Loss

Official v1.0.0-sota-proof release for DIF-FNO (Diffeomorphic Fourier Neural Operator) powered by the D'Agnese Topological Barrier Loss. This architecture strictly resolves grid-folding anomalies (det(J_phi) > 0) across non-convex computational domains (NACA 0012, Star, L-Shape, Annulus) and high-shear physics boundary layers. Key Benchmark Results:- Absolute Topological Integrity: 0.00% grid folding guaranteed across all resolutions.- Zero-Shot Super-Resolution: Seamless extrapolation from 128x128 to 1024x1024 resolution.- Constant Memory Footprint: Fixed 4.53 MB model memory.- 1-Click Verification Suite: Includes run_all_proofs.py for deterministic reproduction.

Abstract

Official v1.0.0-sota-proof release for DIF-FNO (Diffeomorphic Fourier Neural Operator) powered by the D'Agnese Topological Barrier Loss. This architecture strictly resolves grid-folding anomalies (det(J_phi) > 0) across non-convex computational domains (NACA 0012, Star, L-Shape, Annulus) and high-shear physics boundary layers. Key Benchmark Results:- Absolute Topological Integrity: 0.00% grid folding guaranteed across all resolutions.- Zero-Shot Super-Resolution: Seamless extrapolation from 128x128 to 1024x1024 resolution.- Constant Memory Footprint: Fixed 4.53 MB model memory.- 1-Click Verification Suite: Includes run_all_proofs.py for deterministic reproduction.
