دانلود کتاب The Theory of Functions of a Real Variable

This textbook leads the reader by easy stageshroug t h the essential
parts of the theory of sets and theory of measure to the properties
of the Lebesgue integral. The first part of the book gives a general
introduction to functions of a real variable, measure, and
integration, while the second part treats the problem of inverting
the derivative of continuous functions, leading to the Denjoy
integrals, and studies the derivates and approximate derivates of
functions of a real variable on arbitrary linear sets. The author
considers the presentation of this second part as the main purpose
of his book.
