space), high-dimensional geometry (or alternatively, large numbers of random variables), or number-theoretic structures (such as the primes), estimation of sums or integrals of non-negative elementary expressions is a relatively straightforward task, and can be accomplished by a variety of methods....
Here of course is the von Mangoldt function and the Euler totient function. It is conjectured that holds for all , but this is currently only known for , an important result known as the Bombieri-Vinogradov theorem. In a breakthrough paper, Goldston, Yildirim, and Pintz established an imp...
etc The main observation being that the smallest multiple of x that isn't x is 2x. Trivial observations are easy to miss and I didn't think of that until finding the construction. The second seems to be a mix of greedy thinking (use big numbers to escape the sum range when you get ...
AbsandSignum. The syntax ofAbsis the following:(|x|). It looks similar to how we write in on a paper while at the same time allows to avoid ambiguouty (because | is symmetric, there might be problems with it). Euler's totient function was added. ...

Of course, the greatest common divisor is not of this form, but there is a standard trick in analytic number theory to decouple the greatest common divisor, namely to use the classic Gauss identity , with the Euler totient function, to write Inserting this formula and interchanging the sum...
are at least 1. We have thus “localised” the problem to studying the effect of each individual prime independently. (We are able to do this because d(n) is amultiplicative function.) Let’s fix a prime and look at a single term ...
