Born Dec. 22, 1887, in Erode, southern India; died Apr. 26, 1920, near Madras. Indian mathematician.
Although Ramanujan lacked any special mathematical training, he obtained remarkable results in number theory. His most significant study, written with G. Hardy, was on the asymptotic behavior of the function p(n)—the number of ways the number n can be written as a sum of positive terms.
