Srinivasa Ramanujan


Srinivasa Ramanujan was an Indian mathematician who lived during the British Rule in India. Though he had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems considered to be unsolvable.



During his short life, Ramanujan independently compiled nearly 3,900 results (mostly identities and equations). Many were completely novel; his original and highly unconventional results, such as the Ramanujan prime, the Ramanujan theta function, partition formulae and mock theta functions, have opened entire new areas of work and inspired a vast amount of further research.



Known for




  • Landau–Ramanujan constant

  • Mock theta functions

  • Ramanujan conjecture

  • Ramanujan prime

  • Ramanujan–Soldner constant

  • Ramanujan theta function

  • Ramanujan's sum

  • Rogers–Ramanujan identities

  • Ramanujan's master theorem

  • Ramanujan–Sato series
