About the Author

Andrei Bourchtein is a mathematician and educator whose work focuses on the rigorous analysis of convergence in mathematical sequences, series, functions, and integrals. With a deep commitment to clarity and precision, he explores the subtle distinctions that separate true convergence from apparent uniformity, offering readers a wealth of carefully constructed counterexamples that illuminate common pitfalls and deepen understanding. His approach combines theoretical insight with practical illustration, making complex topics accessible to students, researchers, and instructors alike. Bourchtein’s contributions have become valuable resources in advanced calculus and real analysis courses, where his examples challenge assumptions and refine mathematical intuition.
