From Wikipedia, the free encyclopedia
Indian mathematician (born 1951)

The President, Dr. A.P.J. Abdul Kalam presenting Padma Shri to Prof. Ramachandran Balasubramanian, Director of Institute of Mathematical Science, at investiture ceremony in New Delhi on March 29, 2006

Ramachandran Balasubramanian (born 15 March 1951) is an Indianmathematician and was Director of theInstitute of Mathematical Sciences inChennai, India.[1] He is known for his work innumber theory, which includes settling the final g(4) case ofWaring's problem in 1986.[2][3] He is also known for his work inCryptography which includes his famous work with Koblitz, now commonly called theBalu-Koblitz Theorem.[4] His work inAdditive Combinatorics includes his two page paper on additive complements of squares, hence disproving a long standing conjecture ofErdős.[5]

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 theInstitute for Advanced Study in 1980-81.[6]

He was a student ofK. Ramachandra, a lifelong collaborator ofJean-Marc Deshouillers, and co-authored stellar mathematicians likeRam Murty,Kumar Murty,Heath-Brown,N. Koblitz andF. Luca. He was the founder and remains a member of the advisory board of theHardy-Ramanujan Journal.
