Ramanujans

Ramanujans is a surname of Indian origin, most commonly found among Tamil-speaking populations. It denotes people who bear the Ramanujan family name and is best known through the life and work of Srinivasa Ramanujan, the 20th-century Indian mathematician.

Srinivasa Ramanujan (1887–1920) produced substantial original work in number theory, infinite series, and modular forms, much of it documented in notebooks and later validated by later mathematicians. Beginning as a largely self-taught scholar, he corresponded with G. H. Hardy, which led to a collaboration at Cambridge between 1914 and 1919. His discoveries include results on partitions, mock theta functions, and the Ramanujan tau function; several concepts and theorems bear his name, such as Ramanujan's master theorem and Ramanujan primes. His concise proofs and deep intuition left a lasting impact on analytic number theory and mathematical analysis.

Outside of Ramanujan the mathematician, the name remains a surname carried by others of Indian origin. The term Ramanujans in encyclopedic or biographical contexts generally refers to people who share that surname, with Srinivasa Ramanujan as the best-known example.
