The study of dispersal: a conceptual guide as that between BAOs and the usual relational models of modal logic. An important example is the main theorem in Goldblatt and Thomason [Gol-Tho,74] characterizing the elementary modally definable frame classes through their closure under taking generated sub-frames, disjoint unions, .-morphic imag

Entangled Empathy: Politics and Practices as no surprise that the resulting query languages are of the same expressive power. The extended relations of [Yan-Pap,82] are, loosely speaking, nothing else than an embedding of some finite cylindric algebra into an infinite algebra of formulae, and a transformation from finite dimensional relat

Completions and Complete Representations is equal to the converse of its converse). Ideally, our set G of equations will be ., so that any equation valid over fields of relations of a certain rank equipped with the chosen set-theoretically definable operators will be entailed by Γ.

Representing all Cylindric Algebras by Twisting on a Problem of Henkinentable are sought. This line of research is typical: the question one asks here is “what is missing from CAs to be representable?”. But Henkin (himself a prolific contributor to representation theory) turned around this question and instead of asking how much CAs needed to be representable, he aske

Completions, Complete Representations and Omitting Typestions as objects of interest in their own right and go on to discuss questions which naturally arise independently of any connection with logic. But often such purely algebraic results have impact on the logic side. Examples are the undecidability of the representation problem for finite relation al

Crs and Guarded Logics: A Fruitful Contact as that between BAOs and the usual relational models of modal logic.

Cylindric Modal Logicectively. Elaborating this idea, we find that from this modal viewpoint, the standard semantics of first-order logic corresponds to just one of many possible classes of Kripke frames, and that other classes might be of interest as well.
