The Duality of TIme and Information
The states of a computing system bear information and change time, while its events bear time and change information. We develop a primitive algebraic model of this duality of tim...

The Complexity of Model Checking (Collapsible) Higher-Order Pushdown Systems
We study (collapsible) higher-order pushdown systems -- theoretically robust and well-studied models of higher-order programs -- along with their natural subclass called (collapsi...

A Complete Axiomatisation for the Inclusion of Series-Parallel Partial Orders
Series-parallel orders are de ned as the least class of partial orders containing the one-element order and closed by ordinal sum and disjoint union. From this inductive de nition,...

Feasible Proofs of Matrix Properties with Csanky's Algorithm
We show that Csanky’s fast parallel algorithm for computing the characteristic polynomial of a matrix can be formalized in the logical theory LAP, and can be proved correct in LA...

Countably Complementable Linear Orderings
We say that a countable linear ordering L is countably complementable if there exists a linear ordering L, possibly uncountable, such that for any countable linear ordering B, L do...
