In algebra it generates the additive semigroup of the non-negative integer. In analysis it is the radius of the open disk referred to in Schwarz's Lemma. In calculus it is the smallest value of p for which the integral from 1 to infinity of 1/x^p ("1 over x to the p power") diverges. FTP, name the number, the multiplicative identity.
In algebra it generates the additive semigroup of the non-negative integer.
