WebApr 7, 2024 · The sigma symbol (\[\sum \]) is used to represent the sum of an infinite number of terms that follow a pattern. What is Sigma Function? Let x be any integer such that x > 1. The sigma function of positive integer x is defined as the sum of the positive divisor of x. This is generally represented using the Greek letter sigma σ(x). That is WebJul 7, 2024 · The number of divisors function, denoted by τ(n), is the sum of all positive divisors of n. τ(8) = 4. We can also express τ(n) as τ(n) = ∑d ∣ n1. We can also prove that …

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.
