We propose a definition of hierarchical heterogeneous formal specifications, where each module is specified according to its own homogeneous logic. We focus on the specification st...
We propose an approach to support confidentiality for mobile implementations of security-sensitive protocols using Java/JVM. An applet which receives and passes on confidential in...
Resolution refinements called w-resolution trees with lemmas (WRTL) and with input lemmas (WRTI) are introduced. Dag-like resolution is equivalent to both WRTL and WRTI when there...
For a graph G, denote by fk(G) the smallest number of vertices that must be deleted from G so that the remaining induced subgraph has its maximum degree shared by at least k verti...
In this paper we investigate how certain results related to the HananiTutte theorem can be extended from the plane to surfaces. We give a simple topological proof that the weak Ha...
