Probability and stochastic processes used in assessing options

Today, for the proper functioning of financial institutions around the world, it becomes a necessity the knowledge of probabilistic techniques, of Brownian motion theory, of stochastic differential equations. This work present a number of applications of the probability theory and of the stochastic process theory, in one of the most important fields of finances, namely, the theory of options. The approach of the theory of options in this work it is argued by the multitude of their directions for use, namely: in risk control and administration, in financial speculation, etc., the pricing of options being a very important issue met on financial markets. The work is useful both to students of economic specialties, mathematicians, economists and to all those interested in mathematical modeling of economic processes.
