This course is aimed at introducing and developing many of the mathematical tools which are used in applied finance and insurance. ![]() Year 1st year Teaching period Second semester Type Distinctive Credits/Recognition 6 Course disciplinary sector (SSD) SECS-S/06 - mathematical methods of economy, finance and actuarial sciencesĭelivery Formal authority Language English Attendance Obligatory Type of examination Written Prerequisites A good knowledge of basic calculus (Matematica Generale) and of advanced probability (Probability for Finance). For example, the Black–Scholes model prices options as if they follow a geometric Brownian motion, illustrating the opportunities and risks from applying stochastic calculus.īesides the classical Itô and Fisk–Stratonovich integrals, many different notion of stochastic integrals exist such as the Hitsuda–Skorokhod integral, the Marcus integral, the Ogawa integral and more.Oggetto: STOCHASTIC CALCULUS AND MATHEMATICAL FINANCE Oggetto: STOCHASTIC CALCULUS AND MATHEMATICAL FINANCE Oggetto: Academic year 2023/2024 Course ID SEM0174 Teachers Bertrand Lods (Lecturer)Īndrea Bovo (Assistant technician) Degree course Finance Is also used to denote the Stratonovich integral.Īn important application of stochastic calculus is in mathematical finance, in which asset prices are often assumed to follow stochastic differential equations. The Stratonovich integral or Fisk–Stratonovich integral of a semimartingale X The dominated convergence theorem does not hold for the Stratonovich integral consequently it is very difficult to prove results without re-expressing the integrals in Itô form. This enables problems to be expressed in a coordinate system invariant form, which is invaluable when developing stochastic calculus on manifolds other than R n. The main benefit of the Stratonovich integral is that it obeys the usual chain rule and therefore does not require Itô's lemma. ![]() The Stratonovich integral can readily be expressed in terms of the Itô integral, and vice versa. For technical reasons the Itô integral is the most useful for general classes of processes, but the related Stratonovich integral is frequently useful in problem formulation (particularly in engineering disciplines). ![]() The main flavours of stochastic calculus are the Itô calculus and its variational relative the Malliavin calculus. ![]() Since the 1970s, the Wiener process has been widely applied in financial mathematics and economics to model the evolution in time of stock prices and bond interest rates. The best-known stochastic process to which stochastic calculus is applied is the Wiener process (named in honor of Norbert Wiener), which is used for modeling Brownian motion as described by Louis Bachelier in 1900 and by Albert Einstein in 1905 and other physical diffusion processes in space of particles subject to random forces. This field was created and started by the Japanese mathematician Kiyosi Itô during World War II. It allows a consistent theory of integration to be defined for integrals of stochastic processes with respect to stochastic processes. Stochastic calculus is a branch of mathematics that operates on stochastic processes. ![]()
