The decision problem is studied for fragments of second-order linear logic without modalities. It is shown that the structural rules of contraction and weakening may be simulated ...
We prove that tree isomorphism is not expressible in the language (FO + TC + COUNT). This is surprising since in the presence of ordering the language captures NL, whereas tree is...
Fixpoint expressions built from functional signatures interpreted over arbitrary complete lattices are considered. A generic notionof automatonis defined and shown, by means of a ...
We present a game-theoretic model of the polymorphic -calculus, system F, as a fibred category. Every morphism of the model defines an -expanded, -normal form ^ of system F whose...
We consider a class of infinite two-player games on finitely coloured graphs. Our main question is: given a winning condition, what is the inherent blow-up (additional memory) of ...
