Some strange quantifiers,ough in 1958. The semantics is equivalent to Henkin‘s game-theoretic semantics, but unlike Henkin‘s it is compositional. We use second-order formulas to give a new (and with any luck, more manageable) description of this Tarski-style semantics. Finally we apply the new description to present a compo

Pebble games in model theory,e examples are taken from finite model theory, where the Ehrenfeucht game is one of the most useful tools. Extensions of the Ehrenfeucht game to logics more expressive than first-order logic are described, and applications to definability and random models in these logics are outlined.

An interpretive isomorphism between binary and ternary relations,an be interpreted in the other. We establish the stronger result that they are interpretively isomorphic, ., they are mutually interpretable by a pair of interpretations each of which is the inverse of the other.

Complement-equivalence classes on graphs,dges. This defines an equivalence relation where two graphs are equivalent if one can be obtained from the other by a sequence of such operations. We show that given an adjacency-list representation of a digraph ., many fundamental graph algorithms can be carried out on any member of .‘s equivalence
