Aug 26, 2024 · Georg Cantor, German mathematician who founded set theory and introduced the mathematically meaningful concept of transfinite numbers, indefinitely large but distinct from one another. His work was fundamental to the development of function theory, analysis, and topology.

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. Cantor's method of proof of this theorem implies the existence of an infinity of infinities.
Mar 29, 2019 · Kronecker argued that mathematics should be based on whole numbers, and systematically rejected that incipient new branch of mathematics. Kronecker’s attacks ended up provoking in 1884 the first of Cantor’s nervous breakdowns, which he suffered periodically for the rest of his life.
Georg Cantor was a Russian-born mathematician who can be considered as the founder of set theory and introduced the concept of infinite numbers with his discovery of cardinal numbers. He also advanced the study of trigonometric series.
May 28, 2023 · The following gives the original idea of Cantor’s proof. Cantor devised the following function \(f : [0,1]×[0,1] → [0,1]\). First, we represent the coordinates of any point \((x,y) ∈ [0,1]×[0,1]\) by their decimal representations \(x = 0.a_1a_2a_3 ...\) and \(y = 0.b_1b_2b_3....\)
Cantor's continuum problem is simply the question: How many points are there on a straight line in euclidean space? An equivalent question is: How many different sets of integers do there exist?

What impact did Cantor have on mathematics?
Why was Cantor's theory important?
Cantor believed that opposition to the use of actual infinities in mathematics, philosophy, and theology was based upon a common and pervasive error. Whatever mathematicians may have assumed in the past, finite properties could not be predicated in all cases of the infinite.
