Trends in Mathematics is a series that publishes volumes from conferences and lecture series focusing on specific mathematical topics. Its goal is to quickly share current mathematical developments with the community while maintaining high quality and preserving them for future reference. Proposals for publications can be submitted to Birkhäuser Verlag or Birkhäuser Boston Inc. All contributions must undergo a review process similar to that of journals and be checked for correct language use, typically English. Articles without proofs or significant new results are rejected, while high-quality survey papers are welcomed. Organizers must submit manuscripts in a form ready for direct reproduction, using a single dialect of LaTeX. The final version must be submitted within one year of the conference, with a total page count not exceeding 350. The book "Number Theory" is edited by R. P. Bambah, V. C. Dumir, and R. J. Hans-Gill. It includes contributions from various mathematicians on topics such as the prime number theorem, modular equations, the abc-conjecture, and more. The book is published by Birkhäuser and is part of the Trends in Mathematics series. It is a collection of expository and research articles on number theory, compiled in response to an invitation from the Indian National Science Academy for a monograph on selected fields. The book aims to contribute to the further development of number theory.Trends in Mathematics is a series that publishes volumes from conferences and lecture series focusing on specific mathematical topics.
