仿射过程的路径构造

Pathwise construction of affine processes

Nicoletta Gabrielli, Josef Teichmann

摘要:

基于马尔可夫过程的多元时变理论,我们证明了如何将仿射过程识别为某些时变方程的解。结果是J. Kallsen(2006)提出的定理的强版本,该定理提供了仿射过程作为一族独立Lévy过程的时变变换的定律表示。

英文摘要:

Based on the theory of multivariate time changes for Markov processes, we show how to identify affine processes as solutions of certain time change equations. The result is a strong version of a theorem presented by J. Kallsen (2006) which provides a representation in law of an affine process as a time-change transformation of a family of independent Lévy processes.
