The book "Theory and Applications of Special Functions" is a comprehensive collection of works that deal with the theory and applications of special functions in mathematics. It is dedicated to Mizan Rahman, who is recognized for his significant contributions in this field. The articles included in this volume partly stem from a special session of the American Mathematical Society that took place in 2003. The collection not only provides insights into Rahman's own work but also into the research he has supported. The theory of special functions has a long history, dating back to the 18th century when scientists sought solutions to fundamental differential equations. This book reflects the development and diverse applications of this mathematical area and serves as a valuable resource for students and professionals.
