On the Combinatorial Structure of Arrangements of Oriented Pseudocircles
We introduce intersection schemes (a generalization of uniform oriented matroids of rank 3) to describe the combinatorial properties of arrangements of pseudocircles in the plane ...

An infrastructure language for open nets
The structure of open nets, like the Internet, is highly dynamic, as the topology of component networks continuously evolves. In this context, node connectivity is a key aspect an...
