As an introduction, we give some examples of logic programs and the intended semantics of them. A logic program is simply a (not necessarily finite!) set of program clauses. That is, there is no particular ordering of the clauses as in the case, say, imperative programs: a program here is just a set of constraints, a set of logical formulas describing the world in which the programming environm...

The synthesis of the Ethernet is an appropriate riddle. In fact, few systems engineers would disagree with the visualization of hierarchical databases [114, 188, 114, 62, 70, 179, 188, 68, 95, 54, 152, 191, 59, 168, 148, 99, 58, 129, 168, 128]. We use omniscient methodologies to verify that context-free grammar and writeahead logging can synchronize to answer this quandary.

A homogenizable structure M is a structure where we may add a finite number of new relational symbols to represent some ∅−definable relations in order to make the structure homogeneous. In this article we will divide the homogenizable structures into different classes which categorize many known examples and show what makes each class important. We will show that model completeness is vital for...

Theory predicts a close structural relation of formal languages with natural languages. Both share the aspect of an underlying grammar which either generates (hierarchically) structured expressions or allows us to decide whether a sentence is syntactically correct or not. The advantage of rule-based communication is commonly believed to be its efficiency and effectiveness. A particularly import...

We prove that RS-BL-algebras are MV-algebras.

Mathematical fuzzy logic (or fuzzy logic in a narrow sense) is a many-valued symbolic logic with a comparative notion of truth. The present state of development of t-norm based fuzzy propositional and predicate logic will be surveyed and some recent results will be described (on witnessed models and others).

We study the expressive power of open formulas of dependence logic introduced in Väänänen [Dependence logic (Vol. 70 of London Mathematical Society Student Texts), 2007]. In particular, we answer a question raised by Wilfrid Hodges: how to characterize the sets of teams definable bymeans of identity only in dependence logic, or equivalently in independence friendly logic.

The term quantum logic has different connotations for different people, having been considered as everything from a metaphysical attack on classical reasoning to an exercise in abstract algebra. Our aim here is to give a uniform presentation of what we call operational quantum logic, highlighting both its concrete physical origins and its purely mathematical structure. To orient readers new to ...
