To avoid an expensive post-processing phase, needed to compute exact global results, we use a method to a

Completeness Results for Memory Logics,ify and query these structures. In this paper we present sound and complete axiomatizations for some members of this family. We analyze the use of nominals to achieve completeness, and present one example in which they can be avoided.

Logic and Bounded-Width Rational Languages of Posets over Countable Scattered Linear Orderings,s series-rational if and only if it is recognizable by a finite depth-nilpotent algebra if and only if it is bounded-width and monadic second-order definable. This extends previous results on languages of labelled .-free finite and .-posets and on languages of labelled countable and scattered linear orderings.

Positive Fork Graph Calculus,urrences of complementation. We show that this graph calculus is sound, complete and decidable. Moreover, the playful nature of this calculus renders it much more intuitive than its equational counterpart.

Quantitative Comparison of Intuitionistic and Classical Logics - Full Propositional System,y two different approaches, to estimate the asymptotic fraction of intuitionistic tautologies among classical tautologies, obtaining the same results for both. Our results justify informal statements such as “about 5/8 of classical tautologies are intuitionistic”.
