R. Balasubramanian

from Wikipedia, the free encyclopedia

R. Balasubramanian ( Ramachandran Balasubramanian ; born March 15, 1951 in Madras ) is an Indian mathematician who deals with number theory and combinatorics.

Balasubramanian studied at the University of Madras , where he received his bachelor's degree in 1970 and his master's degree in 1972. In 1979 he received his doctorate at the Tata Institute of Fundamental Research in Bombay , a fellow of which he had been since 1978. In 1983 he became a reader , an associate professor in 1985 and a professor in 1990. Since 2000 he has been director of the Institute of Mathematical Sciences (IMS) in Chennai .

In 1986 he and Francois Dress, Jean-Marc Deshouillers determined g (4) to 19 in the Waring problem (the minimum number of fourth powers, to express every natural number as a sum). With Kannan Soundararajan in 1995 he proved a conjecture by Ronald Graham from combinatorial number theory.

He is a member of the Indian Academy of Sciences in Bangalore, the Indian National Academy of Science in New Delhi (whose prize for young scientists he received in 1980) and The National Academy of Sciences in Allahabad. He is President of the Cryptological Society of India in Kolkata. In 2010 he gave a plenary lecture at the International Congress of Mathematicians in Hyderabad . In 2003 he received the French Ordre national du Mérite , in 2006 he received the Padma Shri and in 1990 the Shanti Swarup Bhatnagar Prize for Science and Technology. He is a fellow of the American Mathematical Society .
