# Ramanujan: Essays and Surveys

Share this page *Edited by *
*Bruce C. Berndt; Robert A. Rankin*

A co-publication of the AMS and the London Mathematical Society

This book contains essays on Ramanujan and his work that were written
especially for this volume. It also includes important survey articles in
areas influenced by Ramanujan's mathematics. Most of the articles in the book are
nontechnical, but even those that are more technical contain substantial
sections that will engage the general reader.

The book opens with the only four existing photographs of Ramanujan,
presenting historical accounts of them and information about other people in
the photos. This section includes an account of a
cryptic family history written by his younger brother, S. Lakshmi
Narasimhan. Following are articles on Ramanujan's illness by R. A. Rankin, the
British physician D. A. B. Young, and Nobel laureate S. Chandrasekhar. They
present a study of his symptoms, a convincing diagnosis of the cause of his
death, and a thorough exposition of Ramanujan's life as a patient in English
sanitariums and nursing homes.

Following this are biographies of S. Janaki (Mrs. Ramanujan) and S.
Narayana Iyer, Chief Accountant of the Madras Port Trust Office, who first
communicated Ramanujan's work to the Journal of the Indian Mathematical
Society. The last half of the book begins with a section on
“Ramanujan's Manuscripts and Notebooks”. Included is an important
article by G. E. Andrews on Ramanujan's lost notebook.

The final two sections feature both nontechnical articles, such as Jonathan
and Peter Borwein's “Ramanujan and pi”, and more technical
articles by Freeman Dyson, Atle Selberg, Richard Askey, and G. N. Watson.

This volume complements the book Ramanujan: Letters and Commentary,
Volume 9, in the AMS series, History of Mathematics. For more on Ramanujan, see
these AMS publications, Ramanujan: Twelve Lectures on Subjects Suggested
by His Life and Work, Volume 136.H, and Collected Papers of Srinivasa
Ramanujan, Volume 159.H, in the AMS Chelsea Publishing series.

#### Readership

General mathematical audience.

#### Reviews & Endorsements

A valuable source of initiation into Ramanujan's mathematics for some time to come.

-- B. Sury, Resonance

The book under review assembles a fine collection of essays by several
distinguished authors on a variety of topics that range over Ramanujan's
remarkable life and contributions … This book is a worthy sequel to *Ramanujan: Letters and
Commentary*. It also nicely complements Hardy's classic *Ramanujan: Twelve Lectures on
Subjects Suggested by His Life and Work* and Ramanujan's *Collected Papers*
… Selberg's … article provides many insights and is a magnificent
tribute to Ramanujan … This book, with its delightful collection of
essays and surveys relating to Ramanujan's life and mathematics, is accessible
to, and an inspiration for, laymen, students, and professional mathematicians
alike.
