Cantor diagonalization proof

I'm trying to grasp Cantor's diagonal argument to understand the proof that the power set of the natural numbers is uncountable. On Wikipedia, there is the following illustration: The ….

-1 Diagonalization proceeds from a list of real numbers to another real number (D) that's not on that list (because D's nth digit differs from that of the nth number on the list). But this argument only works if D is a real number and this does not seem obvious to me!The 1981 Proof Set of Malaysian coins is a highly sought-after set for coin collectors. This set includes coins from the 1 sen to the 50 sen denominations, all of which are in pristine condition. It is a great addition to any coin collectio...Aug 6, 2020 · 126. 13. PeterDonis said: Cantor's diagonal argument is a mathematically rigorous proof, but not of quite the proposition you state. It is a mathematically rigorous proof that the set of all infinite sequences of binary digits is uncountable. That set is not the same as the set of all real numbers.

Cantor’s first proof of this theorem, or, indeed, even his second! More than a decade and a half before the diagonalization argument appeared Cantor published a different proof of the uncountability of R. The result was given, almost as an aside, in a pa-per [1] whose most prominent result was the countability of the algebraic numbers. 0 Cantor’s Diagonalization The one purpose of this little Note is to show that formal arguments need not be lengthy at all; on the contrary, they are often the most compact rendering ... Our proof displays a sequence of boolean expressions, starting with (0) and ending with true, such that each expression implies its predecessor in the se-Cantor Diagonalization method for proving that real numbers are strictly uncountable suggests to disprove that there is a one to one correspondence between a natural number and a real number. However, The natural number and the real numbers both are infinite, So, ...Maybe the real numbers truly are uncountable. But Cantor's diagonalization "proof" most certainly doesn't prove that this is the case. It is necessarily a flawed proof based on the erroneous assumption that his diagonal line could have a steep enough slope to actually make it to the bottom of such a list of numerals.

Cantor’s diagonal argument was published in 1891 by Georg Cantor as a mathematical proof that there are infinite sets that cannot be put into one-to-one correspondence with the infinite set of natural numbers. Such sets are known as uncountable sets and the size of infinite sets is now treated by the theory of cardinal numbers which Cantor began.$\begingroup$ Diagonalization is a standard technique.Sure there was a time when it wasn't known but it's been standard for a lot of time now, so your argument is simply due to your ignorance (I don't want to be rude, is a fact: you didn't know all the other proofs that use such a technique and hence find it odd the first time you see it.Cool Math Episode 1: https://www.youtube.com/watch?v=WQWkG9cQ8NQ In the first episode we saw that the integers and rationals (numbers like 3/5) have the same...Lemma 1: Diagonalization is computable: there is a computable function diag such that n = dXe implies diag(n) = d(9x)(x=dXe^X)e, that is diag(n) is the Godel¤ number of the diagonalization of X whenever n is the Godel¤ number of the formula X. Proof sketch: Given a number n we can effectively determine whether it is a Godel¤ number

Cantor's denationalization proof is bogus. It should be removed from all math text books and tossed out as being totally logically flawed. It's a false proof. Cantor was totally ignorant of how numerical representations of numbers work. He cannot assume that a completed numerical list can be square. Yet his diagonalization proof totally …Lemma 1: Diagonalization is computable: there is a computable function diag such that n = dXe implies diag(n) = d(9x)(x=dXe^X)e, that is diag(n) is the Godel¤ number of the diagonalization of X whenever n is the Godel¤ number of the formula X.

It is a curious fact that Cantor’s first proof of this theorem did not use diagonalization. Instead it used concrete properties of the real number line, including the idea of nesting intervals so as to avoid ...Cantor's argument. Cantor's first proof that infinite sets can have different cardinalities was published in 1874. This proof demonstrates that the set of natural numbers and the set of real numbers have different cardinalities.
