A methodology for safety verification of nonlinear systems using barrier certificates has been proposed recently. The condition was stated in a sufficiency form: if there exists a barrier certificate, then the system is safe, in the sense that there is no trajectory starting from a given set of initial states that reaches a given unsafe region. Using the concepts of convex duality and density f...

The Italian white certificates scheme took effect in January 2005.

Legislative Decree of 16th March 1999, n.79,...

The cone of completely positive matrices C∗ is the convex hull of all symmetric rank-1-matrices xx with nonnegative entries. While there exist simple certificates proving that a given matrix B ∈ C∗ is completely positive it is a rather difficult problem to find such a certificate. We examine a simple algorithm which – for a given input B – either determines a certificate proving that B ∈ C∗ or ...
