英文摘要:
The calibration of a local volatility models to a given set of option prices is a classical problem of mathematical finance. It was considered in multiple papers where various solutions were proposed. In this paper an extension of the approach proposed in LiptonSepp2011 is developed by i) replacing a piecewise constant local variance construction with a piecewise linear one, and ii) allowing non-zero interest rates and dividend yields. Our approach remains analytically tractable; it combines the Laplace transform in time with an analytical solution of the resulting spatial equations in terms of Kummer\'s degenerate hypergeometric functions.

中文摘要:
将局部波动率模型校准到给定的期权价格集是数学金融学的一个经典问题。多篇论文都考虑了这一点,并提出了各种解决方案。本文对LiptonSepp2011中提出的方法进行了扩展,即i)用分段线性结构替换分段常数局部方差结构,以及ii)允许非零利率和股息收益率。我们的方法在分析上仍然可行;它将拉普拉斯时间变换与根据Kummer退化超几何函数得到的空间方程的解析解相结合。
