The authors define Awareness-Based Indistinguishability Logic (AIL) with a new semantics for explicit knowledge that is strictly stronger than Fagin-Halpern logic, prove embeddability of the prior logic, and supply a sound and complete axiomatization.
Introduces simplicial secrecy models and primitive secrecy operator S_a φ with sound axiomatization SSL and completeness proof via canonical models for multi-agent cases.
