P. P. Korovkin’s Inequalities—part of the Little Mathematics Library and reprinted by Cheenta Academy, Kolkata under the Cheenta Math & Magic Series—is a concise and elegant introduction to the theory and applications of mathematical inequalities. The book explains classical results such as the Cauchy–Schwarz, Jensen, and Hölder inequalities, while also exploring methods of proof and generalization. Written with clarity and mathematical depth, it helps readers develop intuition for estimation, comparison, and optimization. Ideal for Olympiad students and advanced undergraduates, it remains a timeless gem in mathematical literature.
