Summary: | The concept of vague graph was introduced by Ramakrishna (Int J Comput Cognit 7:51–58,
2009
). Since the vague models give more precision, flexibility, and compatibility to the system as compared to the classical and fuzzy models, in this paper,
the concept of energy of fuzzy graph is extended to the energy of a vague graph
. It has many applications in
physics
,
chemistry
,
computer science
, and other branches of mathematics. We define
adjacency matrix
,
degree matrix
,
laplacian matrix
,
spectrum
, and
energy of a vague graph
in terms of their adjacency matrix. The
spectrum
of a vague graph appears in physics statistical problems, and combinatorial optimization problems in mathematics. Also, the lower and upper bounds for the energy of a vague graph are also derived. Finally, we give some applications of energy in vague graph and other sciences. |
