The book "Analysis on real and complex diversity" by P. Narasimhana is a unique and in-depth study in the field of mathematical analysis that will be of interest to both students and professional mathematicians. This work immerses the reader in the world of manifolds - objects that are the basis of many modern trends in mathematics and physics. R. Narasimhan, known for his contributions to differential geometry and complex analysis, offers the reader not just theoretical calculations, but also practical examples that help to better understand complex concepts. His style of presentation is clear and logical, which makes even the most abstract ideas accessible to perception. The book examines both real and complex varieties, allowing the reader to see the relationships between different areas of mathematics. The main idea of the book is to show how analysis on diversity can be used to solve various problems in mathematics and related disciplines. Narasimhan focuses on topics such as smooth functions, differential forms, and integrals, as well as the importance of Stokes' theorem in the context of manifolds. Readers will be able to see how these concepts are applied to real-world problems, making the material not only theoretically meaningful, but also practically useful. The book will be of interest to senior students of mathematical faculties, graduate students, as well as researchers working in the field of differential geometry and diversity theory .. If you are passionate about mathematics, love to understand complex concepts and want to expand your knowledge of diversity, this work will be a real find for you. The topics raised in the book go beyond pure mathematics and deal with philosophical questions about the nature of space and time. Narasimhan makes us think about how we perceive the world around us and how mathematics can help in this understanding. It raises questions about the relationship between abstract mathematical concepts and real physical phenomena, making reading not only useful, but also fascinating. Narasimhan's style is distinguished by depth and insight. His other well-known works, such as "Geometry and Analysis on Diversity" and "
