Description for Sales People: [SEE ATTACHED FOR COMPLETE TEXT] In recent years stochastic processes have assumed an increasingly important role in the development of the mathematical theory of finance. This self-contained work examines that part of stochastic finance pertaining to option pricing theory. Thus the exposition is confined to areas of stochastic finance that are relevant to the theory, omitting such topics as futures and term-structure. Key features of this work include: * accessible to readers with little or no prior knowledge of stochastic processes or stochastic analysis, * five introductory chapters on stochastic analysis, followed byTable of Contents: 1 Stochastic Integration.- 1.1 Notation and definitions.- 1.2 The predictable ? field.- 1.3 The Ito integral.- 1.4 Quadratic variation of a continuous martingale.- 1.5 The stochastic integral w.r.t. continuous local martingales.- 1.6 Stochastic integral w.r.t. continuous semimartingales.- 1.7 Integration w.r.t. semimartingales.- 2 Ito s Formula and its Applications.- 2.1 Preliminaries.- 2.2 Ito s formula for continuous semimartingales.- 2.3 Ito s formula for r.c.l.l. semimartingales.- 2.4 Applications.- 2.5 Application to geometric Brownian motion.- 2.6 Local time and the Tanaka formula.- 2.7 Brownian motion and the heat equation.- 3 Representation of Square Integrable Martingales.- 3.1 The Ito representation.- 3.2 The Kunita-Watanabe representation.- 4 Stochastic Differential Equations.- 4.1 Preliminaries.- 4.2 Existence and uniqueness of solutions.- 4.3 The Feynman-Kac formula.- 4.4 The Ornstein-Uhlenbeck process (O.

Scholes, stochastic processes have assumed an increasingly important role in the development of the mathematical theory of finance. This work examines, in some detail, that part of stochastic finance pertaining to option pricing theory. Thus the exposition is confined to areas of stochastic finance that are relevant to the theory, omitting such topics as futures and term-structure. This self-contained work begins with five introductory chapters on stochastic analysis, making it accessible to readers with little or no prior knowledge of stochastic processes or stochastic analysis. These chapters cover the essentials of Ito's theory of stochastic integration, integration with respect to semimartingales, Girsanov's Theorem, and a brief introduction to stochastic differential equations. Subsequent chapters treat more specialized topics, including option pricing in discrete time, continuous time trading, arbitrage, complete markets, European options (Black and Scholes Theory), American options, Russian options, discrete approximations, and asset pricing with stochastic volatility. In several chapters, new results are presented. A unique feature of the book is its emphasis on arbitrage, in particular, the relationship between arbitrage and equivalent martingale measures (EMM), and the derivation of necessary and sufficient conditions for no arbitrage (NA). {\it Introduction to Option Pricing Theory} is intended for students and researchers in statistics, applied mathematics, business, or economics, who have a background in measure theory and have completed probability theory at the intermediate level. The work lends itself to self-study, as well as to a one-semester course at the graduate level.
