On the Complexity of Reasoning About Dynamic Policies
We study the complexity of satisfiability for DLP+ dyn , an expressive logic introduced by Demri that allows to reason about dynamic policies. DLP+ dyn extends the logic DLPdyn of...

Cylinders Through Five Points: Complex and Real Enumerative Geometry
It is known that five points in 3 generically determine a finite number of cylinders containing those points. We discuss ways in which it can be shown that the generic (complex) nu...

Increasing the Expressivity of Conditional Functional Dependencies without Extra Complexity
The paper proposes an extension of CFDs [1], referred to as extended Conditional Functional Dependencies (eCFDs). In contrast to CFDs, eCFDs specify patterns of semantically relate...
