Some topological indices of pentagonal double chains [PDF]

ITM Web of Conferences, 2022
In graph theory, lattices are used when some structural part of the graph repeats itself finitely or infinitely many times. They have applications in complex analysis and geometry in mathematics, and also natural applications in chemical graph theory. As

Graph theory in network analysis [PDF]

Social Networks, 1983
For many centuries ideas now embodied in graph theory have been implicit m lay discussions of networks. The explicit hnking of graph theory and network analysis began only in 1953 and has been rediscovered many times since. Analysts have taken from graph theory mainly concepts and termmology; Its theorems, though potentially valuable for the analysis ...
