... for a given k 2 N. We have used it to show that there exists an n 2 N such that k(n) = k for every k 106 . For example, taking k = 106 , we find that q = 106 · (23 1) + 1 = 22000001 is prime and so k(23 · 22000001) = 106 . Unfortunately Lemma 4 does not lead to a proof that k is surjective. Let fk ...

... A number f is called simply normal in the scale of r if (1) holds for k = 1. A number is said to be absolutely normal if it is normal to every base r. It is well-known (see, for example, [6], Theorem 8.11) that almost every number ξ is absolutely normal. We write r ^ s, if there exist integers n, m ...

On the Number of Prime Numbers less than a Given Quantity

It is remarkable, that they have such a simple definition: “p is prime iff p has no other divisors, besides 1 and p”, and at the same time their properties are so hard to explore.

... Say, for example, we want to place 4 balls in 2 identical bins so that each bin gets at least one ball. There are two ways of doing it: Either split the balls 2, 2 or split them 3, 1. These correspond to the ”partitions” 4 = 2 + 2 and 4 = 3 + 1. Let pk (n) denote the number of partitions of n into k ...

Squarefree smooth numbers and Euclidean prime generators
