Ramachandran Balasubramanian (born 15 March 1951) is an Indian mathematician and was Director of the Institute of Mathematical Sciences in Chennai, India. [1] He is known for his work in number theory, which includes settling the final g(4) case of Waring's problem in 1986. [2] [3] He is also known for his work in Cryptography which includes his famous work with Koblitz, now commonly called the Balu-Koblitz Theorem. [4] His work in Additive Combinatorics includes his two page paper on additive complements of squares, hence proving a long standing conjecture of Erdős. [5]

Contents

His works on moments of Riemann zeta function is highly appreciated and he was a plenary speaker from India at ICM in 2010. He was a visiting scholar at the Institute for Advanced Study in 1980-81. [6]

He was a student of K. Ramachandra, a lifelong collaborator of Jean-Marc Deshouillers, and co-authored stellar mathematicians like Ram Murty, Kumar Murty, Heath-Brown, N. Koblitz and F. Luca. He was the founder and remains a member of the advisory board of the Hardy-Ramanujan Journal.
