In his meteoric career he had done brilliant work in Number Theory and Algebraic Geometry. Ramanujan joined the School of Mathematics of the Tata Institute of Fundamental Research as a Research Student in 1957. For instance, 1729 results from adding 1000 (the cube of 10) and 729 (the cube of 9). 51242183 has 3 distinct prime facts and log (log (51242183)) = 2.8765. The general problem referenced above is finding integer solutions to . 2. Elementary Number Theory, Group Theory and Ramanujan Graphs. 2. In number theory, Ramanujan's sum, usually denoted c q (n), is a function of two positive integer variables q and n defined by the formula = (,) =,where (a, q) = 1 means that a only takes on values coprime to q.Srinivasa Ramanujan mentioned the sums in a 1918 paper. It is the sum of the cubes of two numbers 10 and 9. So in early 1913 there was Hardy: a respectable and successful, if personally reserved, British mathematician, who had recently been energized by starting to collaborate with Littlewoodand was being pulled in the direction of number theory by Littlewood's interests there. . Boston, MA: Academic Press, 1988.Anglin, W. S. The Queen of . Ramanujan was profoundly interested in number theory - the study of integers and patterns inherent within them.
