Nettet7. mai 2024 · Double Join of Graphs. In this section, first we define the double join of graphs based on total graph and hence compute the closed formulas of Zagreb indices for the double join of graphs related to the total graph T(G).First, we calculate first Zagreb index of this double join of graphs and then using this formula we derive some examples. NettetIn simplest terms, a graph is a combination of vertices (or nodes) and edges. In the above picture, we have 4 nodes and 4 edges and it is a graph. Graph is a very important data structure to store data which are connected to each other. The simplest example is the network of roads to connect different cities.

INTRODUCTION Despite the term \join" appearing in the graph database literature, such operator cannot be used to combine two distinct graphs, as for table joins in the relational model.
