A note on convergence rate for reflected BSDEs with quadratic generators by penalization method
Guangyan Jia, Peng Luo, Mengbo Zhu
In this paper, we study the convergence rate between reflected backward stochastic differential equations with quadratic generators and their penalized BSDEs. Using techniques of B…
