Theta functions were studied extensively by Ramanujan. This book
provides a systematic development of Ramanujan's results and
extends them to a general theory. The author's treatment of the
subject is comprehensive, providing a detailed study of theta
functions and modular forms for levels up to 12. Aimed at advanced
undergraduates, graduate students, and researchers, the
organization, user-friendly presentation, and rich source of
examples, lends this book to serve as a useful reference, a
pedagogical tool, and a stimulus for further research. Topics,
especially those discussed in the second half of the book, have
been the subject of much recent research; many of which are
appearing in book form for the first time. Further results are
summarized in the numerous exercises at the end of each chapter.

In June 2009, a conference in number theory was held on the
beautiful campus of Infosys in Bangalore. The impetus for
organizing this meeting was to recognize and commemorate K.
Venkatachaliengar, an outstanding, well-known mathematician, who
taught primarily at universities in Bangalore and Mysore for most
of his career. He was born on 8 December, 1908, and so the meeting
marked the centenary of Venkatachaliengar's birth. In the last
several decades of his long life of 95 years, KV, as he was
affectionately known to most of his friends, had become keenly
interested in the life and work of India's greatest mathematician,
Srinivasa Ramanujan, and so it was natural for Ramanujan's first
loves of theta functions, partitions, and q-series to be the focus
of the conference. Accordingly, over 50 mathematicians gathered for
the presentation of 32 lectures in memory of both Ramanujan and KV.
This volume comprises 13 papers by mathematicians who lectured at
the meeting. In addition, three papers on the life and work of KV,
along with a complete list of his publications, are offered.
This unique book provides an innovative and efficient approach to
elliptic functions, based on the ideas of the great Indian
mathematician Srinivasa Ramanujan. The original 1988 monograph of K
Venkatachaliengar has been completely revised. Many details,
omitted from the original version, have been included, and the book
has been made comprehensive by notes at the end of each chapter.The
book is for graduate students and researchers in Number Theory and
Classical Analysis, as well for scholars and aficionados of
Ramanujan's work. It can be read by anyone with some undergraduate
knowledge of real and complex analysis.
