Linear Second-Order Unification and Context Unification with Tree-Regular Constraints
Linear Second-Order Unification and Context Unification are closely related problems. However, their equivalence was never formally proved. Context unification is a restriction of ...

Decidable Expansions of Labelled Linear Orderings
Let M = (A, <, P) where (A, <) is a linear ordering and P denotes a finite sequence of monadic predicates on A. We show that if A contains an interval of order type or -, an...

Linear Higher-Order Matching Is NP-Complete
We consider the problem of higher-order matching restricted et of linear -terms (i.e., -terms where each abstraction x. M is such that there is exactly one free occurrence of x in ...

Linear Orderings of Random Geometric Graphs
Abstract. In random geometric graphs, vertices are randomly distributed on [0, 1]2 and pairs of vertices are connected by edges whenever they are sufficiently close together. Layou...

Logic and Rational Languages of Words Indexed by Linear Orderings
We prove that every rational language of words indexed by linear orderings is definable in monadic second-order logic. We also show that the converse is true for the class of langu...
