In this study,we investigate the well-posedness of exponential growth backward stochastic differcntial cquations(BSDEs)drivcn by a markcd point process(MPP)under unbounded terminal conditions.Our analysis utilizes a f...
In this paper,we study one-dimensional backward stochastic differential cquations fcaturing two refleccting barricrs.When thc tcrminal timc is not ncccssarily bounded or finite and the generator f(t,y.z)exhibits quadr...

In the context of risk measures,the capital allocation problem is widely studied in the literature where different approaches have been developed,also in connection with cooperative game theory and systemic risk.Altho...

We define g-expectation of a distribution as the infimum of the g-expectations of all the terminal random variables sharing that distribution.We present two special cases for nonlinear g where the g-expectation of dis...

In this paper,we investigate a class of nonlinear backward stochastic differential equations(BSDEs)arising from financial economics,and give the sign of corresponding solution.Furthermore,we are able to obtain explici...

We study the quantitative stability of solutions to Markovian quadratic reflected backward stochastic differential equations(BSDEs)with bounded terminal data.By virtue of bounded mean oscillation martingale and change...

This paper is dedicated to solving high-dimensional coupled FBSDEs with non- Lipschitz diffusion coefficients numerically. Under mild conditions, we provided a posterior estimate of the numerical solution that holds f...
We use the functional Ito calculus to prove that the solution of a BSDE with singular terminal condition verifies at the terminal time:lim inf_(t→T)Y(t)=ξ=Y(T).Hence,we extend known results for a non-Markovian termi...
