Bounded Lattice T-Norms as an Interval Category,eralized t-norms are the objects and generalizations of automorphisms are the morphisms of the category. We will prove that, this category is an interval category, which roughly means that it is a Cartesian category with an interval covariant functor.

On Principal Types of BCK-,-Terms,n a relevance relation that he defined between the type variables in a type. We define a symmetric notion of this and call it dependence relation. Then, using the notion of ..-reduction introduced by de Groote, we obtain a characterization of the complete set of principal types of BCK-.-terms.

A Finite-State Functional Grammar Architecture,f the generated types is checked using a simple and efficient dependency calculus. The corresponding dependency structure is extracted from the correctness proof. Using an English example, it is demonstrated that this transduction can be carried out incrementally in the course of composition of the meaning structure.

Hydra Games and Tree Ordinals,epts; an ordinal less than .. is canonically translated into both a hydra and a tree ordinal term, and the reduction graph of the hydra and the normal form of the term syntactically correspond to each other.

,Ehrenfeucht–Fra?ssé Games on Linear Orders,d in a linear order iff the formula is semimodel-satisfied in the corresponding semimodel. The strategy implies the decidability of the theory of linear order, and gives a completion of any formula by one with quantifier rank only 2 larger than the original formula. The strategy generalizes directly to the infinitary theory of linear order.

Numerical Constraints for XML,attention towards numerical keys that permit the specification of upper bounds. Keys, as introduced by Buneman et al., are numerical keys with upper bound 1. Numerical keys are finitely satisfiable, finitely axiomatisable, and their implication problem is decidable in quadratic time.
