Rapid Emergency Response Surveya couple of key ideas that Urquhart pioneered: (i) graph expansion as a tool for distinguishing between easy and hard principles and (ii) “reductive” lower bound arguments, proving via a simulation theorem that an optimal proof cannot bypass the obvious (inefficient) one.

Book 2022ographical essay by Urquhart. This introductory section is followed by papers on algebraic logic and lattice theory, papers on the complexity of proofs, and papers on philosophical logic and history of logic. The final section of the book contains a response to the papers by Urquhart..Alasdair Urquh

Data Mining-Based Variant Subset Features,stricted to those that are crowded, or densely discrete, or openly irresolvable, the latter meaning that every non-empty open subspace is 2-irresolvable. Finally, we give a topological semantics for K4M, where M is the McKinsey axiom.

Tracking Displaced People in Malidy regions changing in time. In this paper, we study a version of DCA incorporating an explicit predicate . of .. We first develop the representation theory of such DCAs by means of the so-called .. Second, we introduce topological models of DCA and develop the corresponding topological representation and duality theory.
