What did Georg Cantor discover?
Georg Cantor, in full Georg Ferdinand Ludwig Philipp Cantor, (born March 3, 1845, St. Petersburg, Russia—died January 6, 1918, Halle, Germany), German mathematician who founded set theory and introduced the mathematically meaningful concept of transfinite numbers, indefinitely large but distinct from one another.
What is Georg Cantor set theory?
He created set theory, which has become a fundamental theory in mathematics. Cantor established the importance of one-to-one correspondence between the members of two sets, defined infinite and well-ordered sets, and proved that the real numbers are more numerous than the natural numbers.
How did Cantor Discover set theory?
Influenced by the notion of ‘condensation point’ (also known as limit or accumulation point today) of a set of real numbers introduced by Heine, Cantor introduced the notion of the derived set of a set of real numbers: For P ⊂ R, Cantor defined the ‘derived set’ of P by P = {x ∈ R : x is an accumulation of P}.
