In mathematics, and specifically in number theory, a divisor function is an arithmetic function related to the divisors of an integer. When referred to as the divisor function, it counts the number of divisors of an integer (including 1 and the number itself). It appears in a number of remarkable identities, including … See more The sum of positive divisors function σz(n), for a real or complex number z, is defined as the sum of the zth powers of the positive divisors of n. It can be expressed in sigma notation as See more For example, σ0(12) is the number of the divisors of 12: while σ1(12) is the … See more In little-o notation, the divisor function satisfies the inequality: More precisely, Severin Wigert showed that: On the other hand, … See more • Weisstein, Eric W.

In Modern Greek, this sound is voiced to the voiced alveolar fricative IPA: [z] when occurring before IPA: [m], IPA: [n], IPA: [v], IPA: [ð] or IPA: [ɣ]. • The uppercase form of sigma (Σ) was re-borrowed into the Latin alphabet—more precisely, the International African Alphabet—to serve as the uppercase of modern esh (lowercase: ʃ).

WebA completely multiplicative function satisfies \(f(ab)=f(a)f(b)\) for all values of \(a\) and \(b.\) Multiplicative functions arise naturally in many contexts in number theory and algebra. The Dirichlet series associated with multiplicative functions have useful product formulas, such as the formula for the Riemann zeta function.
