Ulam Stability of Operators presents a modern, unified, and systematic approach to the field. Focusing on the stability of functional equations across single variable, difference equations, differential equations, and integral equations, the book collects, compares, unifies, complements, generalizes, and updates key results. Whenever suitable, open problems are stated in corresponding areas. The book is of interest to researchers in operator theory, difference and functional equations and inequalities, differential and integral equations.
- Allows readers to establish expert knowledge without extensive study of other books
- Presents complex math in simple and clear language
- Compares, generalizes and complements key findings
- Provides numerous open problems
Researchers in the theories of functional equations, difference equations, operators, approximation, optimization and fixed point theory. Advanced graduate students may have some interest in the field and PhD students are very likely to buy it personally

Dorian Popa
Dorian Popa is the author of numerous papers on Ulam’s type stability of functional equations, differential equations, linear differential operators, and positive linear operators in approximation theory. Other papers deal with the connections of Ulam’s type stability with some topics of multivalued analysis (e.g., the existence of a selection of a multivalued operator satisfying a functional inclusion associated to a functional equation).
