题目：集合竞价的股市交易实验研究报告人：王铎 教授单位：北京大学金融数学系，华南师范大学数学学院时间：10月27日下午3：30地点：数学系107室欢迎广大教师和研究生参

We investigate the partial differential equation (PDE) for pricing interest derivatives in the multi-factor Cheyette Model, that involves time-dependent volatility functions with a special structure. The high dimensional parabolic PDE that results is solved numerically via a modified sparse grid approach, that turns out to be accurate and efficient. In addition we study the corresponding Monte Carlo simulation, which is fast since the distribution of the state variables can be calculated explicitly. The results obtained from both methodologies are compared to the analytical solution existing for bonds and caplets. Keywords: Cheyette Model, Gaussian HJM, Multi-Factor Model, PDE Valuation, Sparse Grid, Monte Carlo Simulation
