Characterizing The Surface of The Embedding
According to the Euler formula we can deduce the genus g of the closed orientable surface defined by the rotation system (that is, the surface on which the underlying multigraph is 2-cell embedded):

Famous quotes containing the words characterizing the and/or surface:
“What ails it, intrinsically, is a dearth of intellectual audacity and of aesthetic passion. Running through it, and characterizing the work of almost every man and woman producing it, there is an unescapable suggestion of the old Puritan suspicion of the fine arts as such—of the doctrine that they offer fit asylum for good citizens only when some ulterior and superior purpose is carried into them.”

“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
