Arithmetic functions

Extremal orders of an arithmetic function

In mathematics, specifically in number theory, the extremal orders of an arithmetic function are best possible bounds of the given arithmetic function. Specifically, if f(n) is an arithmetic function and m(n) is a non-decreasing function that is ultimately positive and we say that m is a minimal order for f. Similarly if M(n) is a non-decreasing function that is ultimately positive and we say that M is a maximal order for f. Here, and denote the limit inferior and limit superior, respectively. The subject was first studied systematically by Ramanujan starting in 1915. (Wikipedia).

Theory of numbers: Multiplicative functions

This lecture is part of an online undergraduate course on the theory of numbers. Multiplicative functions are functions such that f(mn)=f(m)f(n) whenever m and n are coprime. We discuss some examples, such as the number of divisors, the sum of the divisors, and Euler's totient function.
