Average Running Time of the Fast Fourier Transform
... The number of operations of the chirp-z transform (or the approach using (2.5)) is well approximated by @Z(n) for some fixed j3 > 0. A reasonable further assumption is to take p = 2 (for additions and multiplications). Since C(n) is O(n log n), when Assumption (2.7) is valid, the DFT of n numbers ca ...

... • Proof: The only two perfect squares that differ by 1 are 0 and 1 – Thus, any other numbers that differ by 1 cannot both be perfect squares – Thus, a non-perfect square must exist in any set that contains two numbers that differ by 1 – Note that we didn’t specify which one it was! ...

... We will make the assumption that equations (3.1) and (3.2) represent the same factorization. Formally, we say that the factorizations (3.1) and (3.2) are the same except for the order of the factors. With this convention, we have: Theorem 3.2 (Fundamental Theorem of Arithmetic, uniqueness part). The ...

Fermat's Last Theorem
In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c can satisfy the equation an + bn = cn for any integer value of n greater than two. The cases n = 1 and n = 2 were known to have infinitely many solutions. This theorem was first conjectured by Pierre de Fermat in 1637 in the margin of a copy of Arithmetica where he claimed he had a proof that was too large to fit in the margin. The first successful proof was released in 1994 by Andrew Wiles, and formally published in 1995, after 358 years of effort by mathematicians. The theretofore unsolved problem stimulated the development of algebraic number theory in the 19th century and the proof of the modularity theorem in the 20th century. It is among the most notable theorems in the history of mathematics and prior to its proof it was in the Guinness Book of World Records for ""most difficult mathematical problems"".
