英文摘要:
We study the existence of a minimal supersolution for backward stochastic differential equations when the terminal data can take the value +$\\infty$ with positive probability. We deal with equations on a general filtered probability space and with generators satisfying a general monotonicity assumption. With this minimal supersolution we then solve an optimal stochastic control problem related to portfolio liquidation problems. We generalize the existing results in three directions: firstly there is no assumption on the underlying filtration (except completeness and quasi-left continuity), secondly we relax the terminal liquidation constraint and finally the time horizon can be random.

中文摘要:
我们研究了当终端数据以正概率取值为+$\\infty$时,倒向随机微分方程最小上解的存在性。我们处理一般滤波概率空间上的方程和满足一般单调性假设的生成器。利用这个最小上解,我们解决了一个与投资组合清算问题有关的最优随机控制问题。我们从三个方面推广了已有的结果:第一,对基础过滤没有任何假设(除了完备性和拟左连续性),第二,我们放松了终端清算约束,最后时间范围可以是随机的。
