Summary
| Description |
English: Diagram of the Rieger–Nishimura ladder: an intuitionistic Kripke frame whose dual Heyting algebra is the Rieger–Nishimura lattice. The valuation shown corresponds to the generator of the dual algebra, and provides a universal model of intuitionistic logic in one propositional variable. |
