Specifying Graph Languages with Type Graphs [PDF]

open access: yesarXiv, 2017
We investigate three formalisms to specify graph languages, i.e. sets of graphs, based on type graphs. First, we are interested in (pure) type graphs, where the corresponding language consists of all graphs that can be mapped homomorphically to a given type graph.

Graph Laplacians and Stabilization of Vehicle Formations [PDF]

open access: yes, 2001
Control of vehicle formations has emerged as a topic of significant interest to the controls community. In this paper, we merge tools from graph theory and control theory to derive stability criteria for formation stabilization.

Computing Topological Indices for Para-Line Graphs of Anthracene

open access: yesOpen Chemistry, 2019
Atoms displayed as vertices and bonds can be shown by edges on a molecular graph. For such graphs we can find the indices showing their bioactivity as well as their physio-chemical properties such as the molar refraction, molar volume, chromatographic ...

Threshold graph limits and random threshold graphs [PDF]

open access: yesarXiv, 2009
We study the limit theory of large threshold graphs and apply this to a variety of models for random threshold graphs. The results give a nice set of examples for the emerging theory of graph limits.
