| Research Abstract |
In the present project, we applied Malliavin Calculus and operator decomposition techniques to study various problems in applied mathematics. In particular, we provided new simulation techniques for the approximation of solutions of stochastic differential equations driven by jumps. We studied the mathematical properties of these methods and proved that they provide a more accurate and fast method in comparison with past methods of simulation. This type of equation is also used as a model in Mathematical Finance. In this area we provided various formulas for the so called Greeks which measure risk in financial products. Through the use of the infinite dimensional integration by parts formula, we provide various alternatives and we also provided simulations to show the applicability of the results. We also obtain a lower bound estimate for Asian type random variables. We are thinking of applying these results to various problems in filtering.
