证明了在局部性质的温和单调性和正则性假设下,由二维跳跃扩散方程上的非齐次最优停止问题产生的最优停止曲面$(t,y)\映射到x*(t,y)$在时间和空间上是连续的。
We show that optimal stopping surfaces $(t,y)\mapsto x_*(t,y)$ arising from time-inhomogeneous optimal stopping problems on two-dimensional jump-diffusions $(X,Y)$ are continuous (jointly in time and space) under mild monotonicity and regularity assumptions of local nature.
