Srinivasa Ramanujan was a mathematician brilliant beyond comparison who
inspired many great mathematicians. There is extensive literature
available on the work of Ramanujan. But what is missing in the
literature is an analysis that would place his mathematics in context
and interpret it in terms of modern developments. The 12 lectures by
Hardy, delivered in 1936, served this purpose at the time they were
given. This book presents Ramanujan's essential mathematical
contributions and gives an informal account of some of the major
developments that emanated from his work in the 20th and 21st centuries.
It contends that his work still has an impact on many different fields
of mathematical research. This book examines some of these themes in the
landscape of 21st-century mathematics. These essays, based on the
lectures given by the authors focus on a subset of Ramanujan's
significant papers and show how these papers shaped the course of modern
mathematics.
