Spectral study of the Geometric-Arithmetic Index
(Communications in Mathematical and in Computer Chemistry, 2015-11-14)
The concept of geometric-arithmetic index was introduced in the chemical graph theory recently, but it has shown to be useful. One of the main aims of algebraic graph theory is to determine how, or whether, properties of ...
Mathematical Properties of the Hyperbolicity of Circulant Networks
(Hindawi Publishing Corporation Advances in Mathematical Physics, 2015-07-24)
The first works on Gromov hyperbolic spaces deal with finitely generated groups. Initially, Gromov spaces were applied to the study of automatic groups in the science of computation; indeed, hyperbolic groups are strongly ...
