Theorem G — Door Stability

Under weight perturbation, doors with sufficient margin above the threshold are stable — only the epsilon-boundary layer may change.

Constructive Lyapunov Functions via Topology-Preserving Neural Networks

We present a constructive solution to the Lyapunov–Massera–Kurzweil problem via Ontology Neural Networks (ONN), bridging a 60-year gap between existence and con
