Web1 Answer. The proof needs that n ↦ f n ( m) is bounded for each m in order to find a convergent subsequence. But it is indeed not necessary that the bound is uniform in m as well. For example, you might have something like f n ( m) = sin ( n m) e m and the argument still works. Intuitively, we don't need to obtain convergence of the diagonal ...

WebJan 31, 2024 · To calculate the length of the diagonal of a square, multiply the length of the side by the square root of 2: diagonal = √2 × side. Ingrain this relationship into your brain and heart so that never again will you … In set theory, Cantor's diagonal argument, also called the diagonalisation argument, the diagonal slash argument, the anti-diagonal argument, the diagonal method, and Cantor's diagonalization proof, was published in 1891 by Georg Cantor as a mathematical proof that there are infinite sets which cannot … See more Cantor considered the set T of all infinite sequences of binary digits (i.e. each digit is zero or one). He begins with a constructive proof of the following lemma: If s1, s2, ... , sn, ... is any enumeration of elements from T, … See more Ordering of cardinals Assuming the law of excluded middle every subcountable set (a property in terms of surjections) is already countable, i.e. in the surjective image of See more • Cantor's first uncountability proof • Controversy over Cantor's theory • Diagonal lemma See more • Cantor's Diagonal Proof at MathPages • Weisstein, Eric W. "Cantor Diagonal Method". MathWorld. See more The above proof fails for W. V. Quine's "New Foundations" set theory (NF). In NF, the naive axiom scheme of comprehension is modified to avoid the paradoxes by introducing a kind of "local" type theory.
