K. Ananda Rau
K. Ananda Rau (born September 21, 1893 in Madras , † January 22, 1966 in Bombay ) was an Indian mathematician.
Rau attended the Presidency College of the University of Madras and studied from 1914 at the University of Cambridge with Godfrey Harold Hardy , at the same time with S. Ramanujan , with whom he became friends. A relative of Rau, Ramachandra Rao, was a close friend and patron of Ramanujan. In 1917 he won the Smith Prize , in 1919 he received his doctorate from Hardy and returned to India. He became a professor at Presidential College, where he remained until his retirement in 1948 and became a principal of the college.
As a student of Hardy, he initially dealt with analysis, especially summation through general Dirichlet series and here Lambert sums. He proved some general Tauber theorems. Later he dealt with modular functions and the representation of whole numbers as sums of squares. He founded a school of number theory in India.
His wife died early in 1928, his daughter in 1940. He later went blind in one eye.
K. Chandrasekharan is one of his PhD students . Other of his students were Subrahmanyan Chandrasekhar , S. Minakshisundaram (1913–1968), MV Subbarao , Ganapathy Iyer , T. Vijayaraghavan (1902–1955), SS Pillai . He was RK Rubugunday 's paternal uncle .
He later worked in similar fields as Ramanujan. According to R. Narasimhan, he admired Ramanujan without, however, mystifying or romanticizing him like others.
