Walter Rudin

Walter Rudin was an American mathematician and professor of Mathematics at the University of Wisconsin–Madison known for his contributions to mathematical analysis and Rudin's theorem.

Rudin's theorem, also known as the Vitali–Hahn–Saks theorem, is a mathematical result in measure theory that characterizes absolute continuity.

Walter Rudin worked as a professor of Mathematics at the University of Wisconsin–Madison.

Walter Rudin is best known for his contributions to mathematical analysis, particularly in the areas of functional analysis and complex analysis. He has authored several influential textbooks in these areas, such as "Principles of Mathematical Analysis" and "Real and Complex Analysis".

"Principles of Mathematical Analysis" is a widely used textbook written by Walter Rudin. It provides an introduction to real analysis, covering topics such as sequences, series, limits, continuity, differentiation, and integration. The book is known for its rigorous approach and clear exposition, making it a valuable resource for students and researchers in mathematics.
