Ramanujan's legacy: the work of the SASTRA prize winners†

The SASTRA Ramanujan Prize is an annual $10 000 prize given to mathematicians not exceeding the age of 32 for revolutionary contributions to areas influenced by Srinivasa Ramanujan. The prize has been unusually successful in recognizing highly gifted mathematicians at an early stage of their careers who have gone on to shape the development of mathematics. We describe the fundamental contributions of the winners and the impact they have had on current research. Several aspects of the work of the awardees either stem from or have been strongly influenced by Ramanujan's ideas. This article is part of a discussion meeting issue ‘Srinivasa Ramanujan: in celebration of the centenary of his election as FRS’.
