Abstract:
Many problems in mathematical finance (such as the pricing and hedging of complex financial derivatives) can be formulated as high-dimensional integration with dimension as high as hundreds or even thousands. In this talk I will discuss the advances for tackling such high-dimensional problems in mathematical finance. It is shown how the curse of dimensionality can be broken with the optimal convergence rate by using low discrepancy sequences and by properly introducing weights to characterize the importance of variables. I also try to answer why high-dimensional problems in mathematical finance are often of low effective dimension. The necessity and the methods for choosing the right weights in constructing good lattice rules and the methods for dimension reduction are highlighted.
