1. We shall begin with quite elementary and general notions.
2. Classification of integral equations, etc.
3. Applications of the work developed in the last lecture.
About this book :-
"The Theory of Permutable Functions" by "Vito Volterra" is a foundational text in "function theory" and "functional equations". The book explores the properties of "permutable functions", which are functions (f) and (g) that satisfy (f(g(x)) = g(f(x))). Volterra systematically investigates their structure, providing rigorous proofs, examples, and classifications that deepen the understanding of how functions can commute under composition.
Volterra’s work bridges several areas of mathematics, including "real analysis" and complex analysis. The text covers continuity, differentiability, and iteration of permutable functions, highlighting the theoretical and practical significance of these functions in higher mathematics. Each chapter carefully develops methods to study commuting functions, making the material accessible to advanced students while still serving as a reference for researchers.
Renowned for its clarity, depth, and systematic approach, this book remains an essential reference for mathematicians and scholars interested in "functional analysis" and the theory of functions. Its treatment of permutable functions, functional equations, and function composition continues to influence modern research and applications, offering insights into the interplay between structure, iteration, and mathematical properties of functions.

About Author :-
The author
Vito Volterra
(1860–1940) was a renowned Italian mathematician known for his contributions to "functional analysis", "function theory", "permutable functions", and "integral equations". He made significant advances in understanding how functions commute under composition and laid foundational work in the theory of functional equations. Volterra also applied mathematics to real-world problems in physics, ecology, and population dynamics. He taught at the University of Rome and influenced generations of mathematicians and scientists. His work remains a cornerstone in "mathematical research", with "The Theory of Permutable Functions" serving as a seminal reference for both pure and applied mathematics.
