Suitable for both postgraduate students and researchers in the field of operator theory, this book is an excellent resource providing the complete proof of the Brown-Douglas-Fillmore theorem. The book starts with a rapid introduction to the standard preparatory material in basic operator theory taught at the first year graduate level course. To quickly get to the main points of the proof of the theorem, several topics that aid in the understanding of the proof are included in the appendices. These topics serve the purpose of providing familiarity with a large variety of tools used in the proof and adds to the flexibility of reading them independently.

This book is a collated form of the lectures given in a series of events titled “Advanced Functional Analysis and its Applications” conducted at Indian Institute of Technology Hyderabad between years 2019 to 2024. These winter schools focused on various developments on the aforesaid topic. This book is intended to serve the purpose of adding to the knowledge of researchers who are working in Functional Analysis or its allied fields. Additionally, these highlight material that is not included in a typical Functional Analysis or Operator Theory course, but which, if understood, would bring a better level of maturity to those areas. This book serves as a refresher course for college lecturers interested in learning the current developments of Mathematical Analysis. We express our gratitude to our sponsors for their endorsement of the funding for these workshops. We have secured funding from TEQIP MHRD, NBHM, ANRF, as well as from IIT Hyderabad. Finally, each of the lecturers of these workshops have consciously stepped forward to contribute to the success of each and every event. This book is a result of the joint efforts of all those delegates.

This volume brings together fourteen essays authored by distinguished mathematicians from India, offering a panoramic view of current research directions as well as recent historical developments in mathematics in India. The articles cover diverse topics—number theory, operator algebra, operator theory, harmonic analysis, quantum learning, noncommutative geometry and random matrices—showcasing the breadth and depth of contemporary mathematical research. The book provides a vivid snapshot of mathematical thought as it evolves today, connecting tradition with innovation and offering both insight and inspiration to the next generation of mathematicians.The volume opens with an illuminating essay by M. S. Raghunathan, “Some Highlights of Indian Contributions to Mathematics in the 20th Century”, a comprehensive historical account of post-Independence mathematical research in India that will inspire young readers and scholars alike. A special inclusion is the research article “Symmetric Products and Moduli Spaces of Vector Bundles on Curves” by Kyoung-Seog Lee and the late M. S. Narasimhan, completed shortly before Narasimhan’s passing in 2021. This paper, which has already attracted wide attention in the research community, stands as a fitting tribute to his enduring influence in algebraic geometry.
