- The absurd high dimensionality of random graphs
The space of random networks is so ridiculously large that one needs to take drastic measures to make it manageable. - Achieving desired tolerance of a Taylor polynomial on desired interval
For a given interval around a point, how many terms of a Taylor polynomial expanded around that point must be used to achieve a required tolerance? - Definition: Adjacency matrix definition
The adjacency matrix is a matrix of ones and zeros where a one indicates the presence of the corresponding edge in the network. - An algebra trick for finding critical points
