Is there a good reference for facts and theorems about BV real valued functions? I’m looking for something with much more than say Stein and Shakarchi 3, or Evans and Gariepy. Thanks!



Reference request: Functions of bounded variation in one real variable
The following book has a nice and long chapter of BV functions in one variable:


**G. Leoni**, *A First Course in Sobolev Spaces* Graduate Studies in Mathematics
Volume: 181.


Also an excellent book covering a great deal of the material is:


**I. P. Natanson,**
*Theory of functions of a real variable.* 
Translated by Leo F. Boron with the collaboration of Edwin Hewitt. Frederick Ungar Publishing Co., New York, 1955.
