We consider group key agreement (GKA) protocols, used by a group of peers to establish a shared secret key for multicast communications. There has been much previous work to impro...
The number of processors embedded in high performance computing platforms is growing daily to solve larger and more complex problems. The logical network topologies must also suppo...
This paper denes and describes the properties of a multicast virtual topology, the M-array, and a resource-ecient variation, the REM-array. It is shown how several collective op...
In this paper, we introduce localized homology, a theory for finding local geometric descriptions for topological attributes. Given a space and a cover of subspaces, we construct...
We revisit the problem of computing the topology and geometry of a real algebraic plane curve. The topology is of prime interest but geometric information, such as the position of...
