Common knowledge of a finite set of formulas implies a special relationship between syntactic and semantic common … knowledge. If S, a set of formulas held in common knowledge, is implied by the common knowledge of some finite subset of S, and … A is a non-redundant semantic model where exactly S is held in common knowledge, then the following are equivalent: (a …

We provide the monodic fragments of the most important common … knowledge predicate logics with finite Hilbert-style axiomatizations, prove their completeness, and single out a number of …
