WebWhile graphs are typically represented as a set of vertices and a set of edges, they can also be represented by several di erent matrices. This naturally motivates the inquiry as to the nature of a graph’s spectrum. The spectrum of a graph has proven itself to be surprisingly informative about that graph’s characteristics, such WebSpectrum [PE (phycoerythrin)] PE (phycoerythrin) is a fluorescent compound with an excitation peak at 566 nm and an emission peak at 574 nm. It can be excited using a 561 nm laser paired with a 585/20 nm bandpass filter, a configuration that can be found, for example, in the BD Special Order LSRFortessa™ Cell Analyzer.
