Abstract

We present a new dependent type system, NM-DEKL3^3_\infty (Non-Monotone Dependent Knowledge-Enhanced Logic), for formalising evolving knowledge in dynamic environments. The system uses a three-layer architecture separating a computational layer, a constructive knowledge layer, and a propositional knowledge layer. We define its syntax and semantics and establish Soundness and Equational Completeness; we construct a syntactic model and prove that it is initial in the category of models, from which equational completeness follows. We also give an embedding into the μ\mu-calculus and a strict expressiveness inclusion (including the expressibility of non-bisimulation-invariant properties).
