For graphs there exist highly elaborated drawing algorithms. We concentrate here in an analogous way on visualizing relations represented as Boolean matrices as, e.g., in RelView. ...
Hydra games were introduced by Kirby and Paris, for the formulation of a result which is independent from Peano arithmetic but depends on the transfinite structure of 0. Tree ordi...
We show that typability for a natural form of polymorphic recursive typing for rank-2 intersection types is undecidable. Our proof involves characterizing typability as a context ...
We describe a Web-based interactive system, called PILOT, for testing computer science concepts. The strengths of PILOT are its universal access and platform independence, its use...

A netchart is basically a Petri net whose places are located at some process and whose transitions are labeled by message sequence charts (MSCs). Two recent papers showed independe...
