Professor Neena Gupta, a mathematician at the Indian Statistical Institute in Kolkata, has been awarded the '2021 DST-ICTP-IMU Ramanujan Prize for Young Mathematicians from Developing Countries' for her outstanding work in affine algebraic geometry and commutative algebra, informed the Ministry of Science and Technology.

According to the ministry, Professor Gupta is the third woman to receive the Ramanujan Prize, which was first awarded in 2005 and is administered by the Abdus Salam International Centre for Theoretical Physics (ICTP) jointly with the Department of Science and Technology (DST) and the International Mathematical Union (IMU). The DST-ICTP-IMU Ramanujan Prize committee, composed of eminent mathematicians from around the world, commented that Gupta's work "shows impressive algebraic skill and inventiveness".

Professor Gupta's solution for Zariski's cancellation problem, a fundamental problem in algebraic geometry, earned her the 2014 Young Scientists Award by the Indian National Science Academy, who described her solution as 'one of the best works in algebraic geometry in recent years done anywhere'. The 'problem' was posed by one of the most eminent founders of modern algebraic geometry, Oscar Zariski, in 1949. In an interview, Gupta said, "The cancellation problem asks that if you have cylinders over two geometric structures and those have similar forms, can one conclude that the original base structures have similar forms?"

As per the Ministry of Science and Technology, the Ramanujan Prize is given annually to an eminent mathematician who is less than 45 years as on December 31 of the year of the award and has conducted outstanding research in developing countries by the International Centre for Theoretical Physics (ICTP), Trieste, and is sponsored by the Department of Science and Technology (DST), Government of India.
