Systematic Change Impact Determination in Complex Object Database Schemata
Impact analysis is seen as an important technique for controlling the evolution of software systems. Numerous approaches have been proposed which aim to assess the impact of chang...

The Complexity of Finding Replicas Using Equality Tests
We prove (for fixed k) that at least 1 k−1 (n 2 ) − O(n) equality tests and no more than 2 k (n 2 )+O(n) equality tests are needed in the worst case to determine whether a giv...

On the complexity of the resolvent representation of some prime differential ideals
We prove upper bounds on the order and degree of the polynomials involved in a resolvent representation of the prime differential ideal associated with a polynomial differential s...

Complexity of stability and controllability of elementary hybrid systems
In this paper, we consider simple classes of nonlinear systems and prove that basic questions related to their stability and controllability are either undecidable or computationa...
