Here are some of his notable works:
* "The Lebesgue Integral" (1951): A classic textbook on integration theory, covering Lebesgue measure and integration in detail.
* "A First Course in Mathematical Analysis" (1962): A comprehensive introduction to real analysis, suitable for undergraduate students.
* "Lectures on Integration" (1965): A more advanced text on integration theory, focusing on abstract measure spaces and various types of integrals.
In addition to these books, he also published numerous research papers on topics such as:
* Measure and integration
* Set theory
* Functional analysis
* Differential equations
His work has been highly influential in the development of modern mathematical analysis.
