On the Nature of Connectivity Types

The purpose of studying connectivity types is to look for a way to classify in a fairly comprehensive manner all critical circular planar n-boundary node graphs. We start by looking at the four-boundary node and ¯ve-boundary node graphs. Moreover, by listing all the examples of the two cases, it is possible that we can ¯nd bases of connectivity types that imply a set of larger connectivity types. This would allow us to come up with a method of generalizing to n-boundary node critical circula
