In this paper we show that there is an analytic and computable dynamical system with a hyperbolic sink s such that the basin of attraction of s is not computable. As a consequence, the problem of determining basins of attraction for analytic hyperbolic systems is not, in general, algorithmically solvable. 1 Summary of the paper Dynamical systems are fascinating mathematical objects. They can be...

As IP technologies providing both tremendous capacity and the ability to establish dynamic secure associations between endpoints emerge, Virtual Private Networks (VPNs) are going through dramatic growth. The number of endpoints per VPN is growing and the communication pattern between endpoints is becoming increasingly hard to forecast. Consequently , users are demanding dependable, dynamic con-...
