Theory of Functions of a Real Variable, Vol. I written by
I.P.Natanson . Translated from Russina by
Leo F Boron , Department of Mathematics, University of Michigan.
With the editorial collaboration of, and with annotations by
Edwin Hewitt, Professor of Mathematics, University of Washington.
This book treats the theory of functions of a real variable from a largely classical point of view. It is designed for use in the current
Soviet Universty Program, by students in their third year of university studies. The author is a distinguished Soviet sientist and teacher, who
has evidently lectured for a number of years on the subject matter of present book. The book has been through two earlier editions, one in 1941
under the title Foundation of the Theory of Functions of a Real Variable and a second in the Ukrainian language, with various extensions by S.
I. Zuhovichii.
This book cover the following topics.
