A mathematics professor from Indian Statistical Institute (ISI), Kolkata has become theyoungest person to ever receive the prestigious Shanti Swarup Bhatnagar Prizeat the age of 35.Dr Neena Guptawasawarded the Prizeforhaving solved a 70-year-old mathematics puzzle called the Zariski Cancellation Problem.Dr Guptais not just the youngest, but alsoonlythe third woman to winthe honourtill date.

Gupta is an Associate Professor at the Statistics and Mathematics Unit at ISI, Kolkata. She graduated with an Honours in Mathematics from Bethune College, Kolkata in 2006, after whichshe went on tostudy Mathematics at the post-graduate level from ISI. She entered the Indian academic ring witha PhD in Algebraic Geometry.Guptahasalso won theIndian National Science Academy–Young Scientist Award in 2014 for her work on theZariski Cancellation Problem, soon after she first published her research paper on it in 2014.

The Zarinski Cancellation Problem

Inrecent years, Dr Gupta has provided solutions to two open problems in mathematics – one, posed by Oscar Zariski (1899-1986), one of the founders of modern Algebraic Geometry.Gupta describes these open mathematical conjectures as problems which can be easily explained to mathematicians but are very difficult to solve, in aninterview with Research Matters. The ‘Zariski Cancellation Problem’, which has earned Gupta the SSB prize,hasintrigued mathematicians around the globe ever since a version of it was proposed by O Zariski in 1949.

Bythe early 21st century, several eminent mathematicians had triedtheir hand at asolve forthe Zariski Cancellation Problem, which remained open for about 70 years beforeGupta’s complete solution came alongin 2014.

“I knew this problem right from my PhD days, but I never imagined that I will be able to solve it,” shetold Research Matters. The solutions provided by Dr Gupta have given both insights and inspiration to young researchers as they can initiate research into other associated conjectures, which remain open.

Shanti Swarup BhatnagarAward

The Shanti Swarup Bhatnagar Prize is announced every year on 26 September to celebrate the Council of Scientific and Industrial Research’s (CSIR) Foundation Day.This prize is given out to recognise a handful of scientists and researchers across many disciplines for having madeoutstanding contributions to science and technology in India.The awards are given outacross seven categories,andinclude a citation, a commemorative plaque, a cashprize of Rs 5 lakh, and additionally, an endowment of ₹15,000 per month up to the age of 65 years. They receive an award from the Prime Minister.

There are seven categories in the following disciplines- Biological Sciences, Chemical Sciences, Earth, Atmosphere, Ocean and Planetary Sciences, Engineering Sciences, Mathematical Sciences, Medical Sciences, Physical Sciences.

Twelve scientists from different institutions across the country have been chosen for the prestigious Shanti Swarup Bhatnagar Prize for 2019. Thewinners of the awards includeDr Kayarat Saikrishnan of Indian Institute of Science Education and Research, Pune and Dr Soumen Basak of National Institute of Immunology, New Delhi (biological sciences), Dr Raghavan B Sunoj of IIT, Bombay and Dr Tapas Kumar Maji of Jawahar Lal Nehru Centre for Advanced Scientific Research, Bengaluru (Chemical Sciences), and Dr Dishant Mayur Bhai Pancholi of Institute of Mathematical Sciences, Chennai, and Dr Neena Gupta of Indian Statistical Institute, Kolkata (Mathematical Sciences).

The other scientists on the list also include Dr Dheeraj Kumar of International Centre for Genetic Engineering and Biotechnology, New Delhi and Dr Mohammad Javed Ali of LV Prasad Eye Institute, Hyderabad (Medical Sciences), Dr Aninda Sinha of IISc, Bengaluru, and Dr Shankar Ghosh of TIFR, Mumbai (Physical Sciences), Dr Subimal Ghosh of IIT, Bombay (Earth, Atmosphere, Ocean and Planetary Sciences), and Dr ManikVarma (Microsoft Research India, Bengaluru (Engineering Sciences).

Who is Shanti Swarup Bhatnagar?

Dr Shanti Swarup Bhatnagarwas the Founder Director and the first Director-General of CSIR and is considered to be “the Father of research laboratories” in India. He got this monikerfor having established twelve nationally-recognised laboratoriesover the course of his lifetime.
