摘要： High dimensionality and discontinuity are two outstanding challenges in computational finance, such as in the problems of pricing and hedging of complex financial derivatives. In this talk I will touch briefly on recent advances in understanding the success of quasi-Monte Carlo (QMC) methods for high dimensional problems in mathematical finance, and propose new dimension reduction methods and smoothing methods that deal with the “curse of dimensionality” and discontinuity for typical problems in mathematical finance. Numerical experiments demonstrate that the proposed methods significantly increase the efficiency of QMC methods for pricing options and estimating the Greeks (or sensitivities).
