Atsushi Takeuchi

摘要:

考虑具有漂移、扩散和跳跃项的跳跃型随机微分方程。研究了求解过程中密度的对数导数,在扩散项和跳跃项系数的一致椭圆条件下,得到了Bismut-Elworthy-Li型公式.我们的方法是基于柯尔莫哥洛夫向后方程,充分利用马尔可夫性质的过程。

英文摘要:

Consider jump-type stochastic differential equations with the drift, diffusion and jump terms. Logarithmic derivatives of densities for the solution process are studied, and the Bismut-Elworthy-Li type formulae can be obtained under the uniformly elliptic condition on the coefficients of the diffusion and jump terms. Our approach is based upon the Kolmogorov backward equation by making full use of the Markovian property of the process.
