Encyclopedia
Kanakanahalli Ramachandra (1933 August 18, Mysore, India – 2011 January 17) was an Indian mathematician working in analytic number theory
.
Ramanujan.
Ramachandra completed his graduation and post graduation from Central College, Bangalore.
Later, he worked as a lecturer in BMS College of Engineering. Ramachandra also served a very short stint of
only six days as a teacher in the Indian Institute of Science
, Bangalore.
Ramachandra went to the Tata Institute of Fundamental Research
(TIFR), Bombay, for his graduate studies in 1958. He obtained his Ph.D. from University of Mumbai
in 1965; his doctorate was guided by K. G. Ramanathan.
and after retirement joined the National Institute of Advanced Studies
, Bangalore where he worked till 2011, the year he died. During the course of his lifetime, he published over 200 articles, of which over 170 have been cataloged by Mathematical Reviews
.
His work was primarily in the area of prime number theory, working on the Riemann zeta function and allied functions. Apart from prime number theory, he made substantial contributions to the theory of transcendental number theory
, in which, he is known for his proof of the six exponentials theorem
, which is done independently of Serge Lang
. He also contributed to many other areas of number theory. His Erdős number
was 1.
In 1978 he founded the Hardy–Ramanujan journal
, and published it on behalf of the Hardy–Ramanujan society until his death.
Analytic number theory
In mathematics, analytic number theory is a branch of number theory that uses methods from mathematical analysis to solve problems about the integers. It is often said to have begun with Dirichlet's introduction of Dirichlet L-functions to give the first proof of Dirichlet's theorem on arithmetic...

Early career
After his father's death at age 13, he had to look for a job. Ramachandra worked as a clerk at the Minerva Mills where Ramachandra’s father had also worked. In spite of taking up a job quite remote from mathematics, Ramachandra studied number theory all by himself in his free time; especially the works ofRamanujan.
