We prove that one can express the vertex-minor relation on finite undirected graphs by formulas of monadic second-order logic (with no edge set quantification) extended with a p...
We propose a definition of locality for properties of geometric graphs. We measure the local density of graphs using region-counting distances [8] between pairs of vertices, and w...
We address two problems of technical authors in structured environments: (1) Structure definitions of the SGML school are limiting: they require one primary hierarchy and do not c...
Abstract. The emerging technology of interacting systems calls for new forto ensure their reliability. Concurrent games are paradigmatic abstract models for which several logics ha...
Deterministic graph grammars generate regular graphs, that form a structural extension of configuration graphs of pushdown systems. In this paper, we study a probabilistic extensio...
