## Description

*An Introduction to the Mathematics of Financial Derivatives *is a popular, intuitive text that eases the transition between basic summaries of financial engineering to more advanced treatments using stochastic calculus. Requiring only a basic knowledge of calculus and probability, it takes readers on a tour of advanced financial engineering. This classic title has been revised by Ali Hirsa, who accentuates its well-known strengths while introducing new subjects, updating others, and bringing new continuity to the whole. Popular with readers because it emphasizes intuition and common sense,* An Introduction to the Mathematics of Financial Derivatives *remains the only "introductory" text that can appeal to people outside the mathematics and physics communities as it explains the hows and whys of practical finance problems.

## Key Features

- Facilitates readers' understanding of underlying mathematical and theoretical models by presenting a mixture of theory and applications with hands-on learning
- Presented intuitively, breaking up complex mathematics concepts into easily understood notions
- Encourages use of discrete chapters as complementary readings on different topics, offering flexibility in learning and teaching

## Readership

Upper-division undergraduates and graduate students seeking an introduction to the mathematics and concepts underlying financial derivatives in specific and investment vehicles (options, futures, and other financial engineering products) in general.

## Reviews

*"This text introduces quantitative tools used in pricing financial derivatives to those with basic knowledge of calculus and probability. It reviews basic derivative instruments, the arbitrage theorem, and deterministic calculus, and describes models and notation in pricing derivatives, tools in probability theory, martingales and martingale representations, differentiation in stochastic environments, the Wiener and Lévy processes and rare events in financial markets…"--**ProtoView.com,* February 2014*"Ali Hirsa has done a superb job with this third edition of the very popular Neftci's An Introduction to the Mathematics of Financial Derivatives. New chapters and sections have been added covering in particular credit derivatives (Chapter 23) and jump processes and the associated partial integro-differential equations. The new material on numerical methods, in particular on Fourier techniques (Chapter 22) and calibration (Chapter 25), and added examples and exercises are very welcome. Overall, this new edition offers substantially more that the previous one in all of its chapters. This is a unique sophisticated introduction to financial mathematics accessible to a wide audience. Truly remarkable!"--***Jean-Pierre Fouque, University of California, Santa Barbara**"The publication of this expansive and erudite text in a new edition by one of the most highly respected scholars in the field should be a welcome event for practitioners and academics alike."--

**Lars Tyge Nielsen, Columbia University**

"There are many books on mathematics, probability, and stochastic calculus, but relatively few focus entirely on the pricing and hedging of financial derivatives. I have used the second edition for finance and financial engineering classes for years, and will continue with the third edition; the book will no doubt remain a valuable reference for industry practitioners as well."--

**Robert L. Kimmel, National University of Singapore**

"An excellent introduction to a wide range of topics in pricing financial derivatives with highly accessible mathematical treatment. Its heuristic style in explaining basic mathematical concepts relevant to financial markets greatly facilitates understanding the fundamentals of derivative pricing."--

**Seppo Pynnonen, Unversity of Vaasa**

"What makes this introductory text unique for students or practitioners without a major in mathematics or physics is that it provides the most helpful heuristics while clearly stating how or why the concepts are useful for practical problems in finance. The timely additions on credit derivatives and PDEs provide considerable value-added in comparison to the second edition."--**Mishael Milaković, University of Bamberg**
