Strong solutions of mean-field FBSDEs and their applications to multi-population mean-field games
Kihun Nam, Yunxi Xu
We study the existence of strong solutions for mean-field forward-backward stochastic differential equations (FBSDEs) with measurable coefficients and their implication on the Nash…
