Other Possible Meanings
The theory mentioned above does not directly relate to the concept of mathematical singularity as a value at which a function isn't defined. For that, see for example isolated singularity, essential singularity, removable singularity. The monodromy theory of differential equations, in the complex domain, around singularities, does however come into relation with the geometric theory. Roughly speaking, monodromy studies the way a covering map can degenerate, while singularity theory studies the way a manifold can degenerate; and these fields are linked.

Famous quotes containing the word meanings:
“Man cannot bury his meanings so deep in his book, but time and like-minded men will find them. Plato had a secret doctrine, had he? What secret can he conceal from the eyes of Bacon? of Montaigne? of Kant? Therefore, Aristotle said of his works, “They are published and not published.””
—Ralph Waldo Emerson (1803–1882)
