....has cofree coalgebras then any logic L for Sigma coalgebras has a smallest expressive extension L . The idea of the construction is simply to add, for each behavioural covariety B, a formula defining B. That this results indeed in a logic in the sense of Definition 4 follows from [11], Theorem 4.12. The extension L is the smallest expressive extension in the sense that L definable classes are also definable in any other expressive extension of L. 2 Logics Admitting Final Semantics The notion of a logic admitting final semantics is adapted from Mahr and Makowsky [15] ....
.... Theta D) the class (B) V is L definable and, therefore, has a fully abstract final coalgebra. Now apply Theorem 2. Let L be a logic having precisely the behavioural covarieties as definable classes. That L is a logic in the sense of Definition 4 follows from Theorem 4. 12 in [11]. Define, for all C 2 Set, L C as the disjoint union LC L C and j= C = j= C [ j= C ) Then L is a fragment of the expressive logic L . Since L definable classes are quasi covarieties and L definable classes are behavioural covarieties, L definable classes are ....
