Derived Set (mathematics)
In mathematics, more specifically in point-set topology, the derived set of a subset S of a topological space is the set of all limit points of S. It is usually denoted by S′.
The concept was first introduced by Georg Cantor in 1872 and he developed set theory in large part to study derived sets on the real line.

Famous quotes containing the words derived and/or set:
“In the case of our main stock of well-worn predicates, I submit that the judgment of projectibility has derived from the habitual projection, rather than the habitual projection from the judgment of projectibility. The reason why only the right predicates happen so luckily to have become well entrenched is just that the well entrenched predicates have thereby become the right ones.”
—Nelson Goodman (b. 1906)
“Racism is when you have laws set up, systematically put in a way to keep people from advancing, to stop the advancement of a people. Black people have never had the power to enforce racism, and so this is something that white America is going to have to work out themselves. If they decide they want to stop it, curtail it, or to do the right thing ... then it will be done, but not until then.”
—Spike Lee (b. 1956)
