arXiv 2022年
作者: Baker, Graeme Shkolnikov, Mykhaylo Program in Applied & Computational Mathematics Princeton University PrincetonNJ08544 United States ORFE Department Bendheim Center for Finance and Program in Applied & Computational Mathematics Princeton University PrincetonNJ08544 United States
We consider a probabilistic formulation of a singular two-phase Stefan problem in one space dimension, which amounts to a coupled system of two McKean-Vlasov stochastic differential equations. In the financial context... 详细信息

arXiv 2023年
作者: Reese, Tanner M. Wehr, Jan Department of Mathematics University of Arizona TucsonAZ85721 United States Department of Mathematics and Program in Applied Mathematics University of Arizona TucsonAZ85721 United States
We study systems of differential equations driven by functions of a single Wiener process. In the limit of fast oscillations, we show that the solution process converges in law to the process defined by an SDE system ... 详细信息
