基于g-期望的随机序

Stochastic ordering by g-expectations

Sel Ly, Nicolas Privault

摘要:

在非线性g-期望和g-评价下,得到了扩散过程凸单调g-随机序的充分条件。我们的方法依赖于前向后随机微分方程的比较结果和相关的半线性抛物型偏微分方程的解的凸性,单调性和连续依赖性的几个扩展。在不同的套期保值组合约束条件下,未定权益价格比较的应用。

英文摘要:

We derive sufficient conditions for the convex and monotonic g-stochastic ordering of diffusion processes under nonlinear g-expectations and g-evaluations. Our approach relies on comparison results for forward-backward stochastic differential equations and on several extensions of convexity, monotonicity and continuous dependence properties for the solutions of associated semilinear parabolic partial differential equations. Applications to contingent claim price comparison under different hedging portfolio constraints are provided.
