Short Transitive Signatures for Directed Trees
A transitive signature scheme allows to sign a graph in such a way that, given the signatures of edges (a, b) and (b, c), it is possible to compute the signature for the edge (or ...

Emulating Direct Products by Index-Shuffle Graphs
In the theoretical framework of graph embedding and network emulations, we show that the index-shuffle graph (a bounded-degreehypercube-like interconnection network, recently intr...

Feasibility of Motion Planning on Directed Graphs
Because of irreversibility of movements, motion planning on directed graphs is much more intricate than that on graphs. Recently we showed that the feasibility of motion planning o...

Creating Minimal Vertex Series Parallel Graphs from Directed Acyclic Graphs
Visualizing information whose underlying graph is directed acyclic is easier if the graph is Minimal Vertex Series Parallel (MVSP). We present method of transforming any directed ...

Directed Graphs of Entanglement Two
Entanglement is a complexity measure for directed graphs that was used to show that the variable hierarchy of the propositional modal µ-calculus is strict. While graphs of entangl...
