What problem does it solve?
This skill helps formalize and explore statements that are independent of ZFC by constructing forcing extensions and verifying which statements hold in the extended models.
Core Features & Use Cases
- Formalize independence arguments: annotate and validate where additional axioms are needed.
- Lean 4 integration: provides templates and skeletons to model forcing notions and generic extensions within Lean 4.
- Educational use: illustrate classical independence results (e.g., CH) with guided Lean sketches.
Quick Start
Provide a minimal Lean 4 sketch showing that a statement is independent of ZFC by constructing a forcing extension.
