Graph equations for line graphs, blitact graphs and blict graphs

Journal of Discrete Mathematical Sciences and Cryptography, 2005
Abstract In this paper, we solve the graph equations L(G)=B m (H), L(G) and . The equality symbol ‘=’ stands for an isomorphism between two graphs.

Graphs and homomorphisms

Oxford lecture series in mathematics and its applications
This is a book about graph homomorphisms, intended to introduce this exciting topic to a wide audience. It attempts to bring together what the authors see as the highlights of the theory and its many applications, and could be read as a sampler of this

Cardinality of Hajós Graphs and Hajós Fuzzy Graphs on Fan Graph, Lollipop Graph, Friendship Graph, Tadpole Graph and Crown Graph

International Journal of Fuzzy Mathematical Archive
Hajos Fuzzy graph is a new fuzzy graph obtained by applying a binary operation, named Hajos construction, on two fuzzy graphs. The Hajos construction on two (fuzzy) graphs produces many different (fuzzy) graphs depending on the choice of vertices and edges.

Conceptual Graphs Are Also Graphs

2014
The main objective of this paper is to add one more brick in building the CG model as a knowledge representation model autonomous from logic. The CG model is not only a graphical representation of logic, it is much more: it is a declarative model encoding knowledge in a mathematical theory, namely labelled graph theory, which has efficient computable ...

Specifying architecture of knowledge graph with data graph, information graph, knowledge graph and wisdom graph

2017 IEEE 15th International Conference on Software Engineering Research, Management and Applications (SERA), 2017
Knowledge graphs have been widely adopted, in large part owing to their schema-less nature. It enables knowledge graphs to grow seamlessly and allows for new relationships and entities as needed. Knowledge graph has become a powerful tool to represent knowledge in the form of a labelled directed graph and to give semantics to textual information.

HYPERMETRIC GRAPHS

The Quarterly Journal of Mathematics, 1993
Several classes of finite distance spaces and the corresponding classes of graphs are considered \((l_ 1\)-space, \(h\)-embeddable, spherical, hypermetric and of negative type). The focus is on hypermetric graphs. Several characterization results for hypermetric graphs are given. In particular, connected regular hypermetric graphs of diameter \(\leq 2\)
