Note: There does not seem to be (Edit: this has changed since then) a specific tag related to Ramanujan so I have put this under "sequences-and-series" and noting that nowadays most of Ramanujan's work is studied under modular-forms I have added that tag.

Abstract. When Ramanujan died in , he left behind an incomplete, unpublished manuscript in two parts on the partition function p(n) and, in contemporary terminology, Ramanujan’s tau-function τ(n).The influence of this manuscript cannot be underestimated. I am curious to know (some words or reasoning about how to justify) why to prove that the so-called Ramanujan $\tau$ is a multiplicative function is (was) very difficult. In this Wikipedia is showed the conjecture due to Ramanujan, and I see that the function $\tau(n)$ is defined from the first formula of the Wikipedia's article. Then I suspect.

In his paper On certain Arithmetical Functions published in Transactions of the Cambridge Philosophical Society, XXII, No.

9, Ramanujan makes some bold claims about the tau function. Srinivasa Ramanujan FRS (/ ˈ s r ɪ n ɪ v ɑː s r ɑː ˈ m ɑː n ʊ dʒ ən /; born Srinivasa Ramanujan Aiyangar; 22 December – 26 April ) was an Indian mathematician who lived during the British Rule in India.

Though he had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and Born: 22 DecemberErode, Madras.

$\begingroup$ Also Ramanujan was interested in representations of numbers by quadratic forms, and in particular the number of representations of an integer as the sum of an note on Ramanujans arithmetical function [tau book number of squares.

Exact formulas were known in a number of cases already, and he might have been trying to extend these. As I recall, his famous paper begins by writing down identities for the. Ramanujan expansions. If f(n) is an arithmetic function (i.e.

a complex-valued function of the integers or natural numbers), then a convergent infinite series of the form: = ∑ = ∞ ()or of the form: = ∑ = ∞ ()where the a k ∈ C, is called a Ramanujan expansion of f(n).

Ramanujan found expansions of some of the well-known functions of number theory. All of these results are. † This functional equation appears to have been first stated by Wilton, J.

This book provides an introduction to these two important subjects and to some of the topics in number theory that are inextricably intertwined with them, including the theory of partitions, sums of squares and triangular numbers, and the Ramanujan tau function.

I have read this book in my first year at my college- BITS Pilani. Though everyone is aware about Dr. Ramanujan yet several children in India still don't know about it which is quite disheartening.

It was quite a compelling read and I readily recommend this book 5/5(3). Ramanujan, Srinivasa (), ”On certain arithmetical functions”, Trans. Cambridge Philos. Soc. 22 (9): – Serre, J-P.

In his paper On certain arithmetical functions, Ramanujan defined the so.

It's a very long list. I am mentioning a few here: 1. Ramanujan's theta functions. They are some formal series with excellent analytical properties. They have huge applications within and outside mathematics.

Ramanujan's mock theta functions. Note: Citations are based on reference standards. However, formatting rules can vary widely between applications and fields of interest or study.

Garvan conjectured that two families of Ramanujan's theta functions are genuinely different from Jacobi's theta functions, not just the same functions in disguise.

They linked Ramanujan's functions to partitions of a given integer—the ways of writing an integer as a sum of smaller integers. Functions are equations that can be drawn as graphs on an axis, like a sine wave, and produce an output when computed for any chosen input or value.

In the letter, Ramanujan wrote down a handful. Hardy and others strongly urged that notebooks be edited and published, and the result is this series of books.

Srinivasa Ramanujan () was an Indian mathematician who made great and original contributions to many mathematical fields, including complex analysis, number theory, infinite series, and continued fractions. He was "discovered" by G. H. Hardy and J. E. Littlewood, two world-class mathematicians at Cambridge, and enjoyed an extremely fruitful period of .Abstract.

When Ramanujan died inhe left behind an incomplete, unpublished manuscript in two parts on the partition function p(n) and, in contemporary terminology, Ramanujan’s tau-function τ(n).The first part, beginning with the Roman numeral I, is written on 43 pages, with the last nine comprising material for insertion in the foregoing part of the manuscript.This is a list of mathematical symbols used in all branches of mathematics to express a formula or to represent a constant.
