Excerpt: In mathematics, the Bernoulli numbers Bn are a sequence of rational numbers with deep connections to number theory. They are closely related to the values of the Riemann zeta function at negative integers. There are several conventions for Bernoulli numbers. The most common has Bn = 0 for all odd n other than 1, and B1 = -1/2, but some authors use B1 = +1/2 and some write Bn for B2n. The values of the first few nonzero Bernoulli numbers are (more values below): The Bernoulli numbers were discovered ar...
