In this paper, we introduce a new method to study the doubly reflected backward stochastic differential equation driven by G-Brownian motion (G-BSDE). Our approach involves approximating the solution through a family of penalized reflected G-BSDEs with a lower obstacle that are monotone decreasing. By employing this approach, we establish the well-posedness of the solution of the doubly reflected G-BSDE with the weakest known conditions, and uncover its relationship with the fully nonlinear partial differential equation with double obstacles for the first time.

  1. Mind the jumps: when 2BSDEs meet semi-martingales

    math.PR 2025-07 conditional novelty 7.0 of 10

    Semi-martingale second-order BSDEs with jumps are proved well-posed over a unified class of diffusions, pure-jump processes, and discrete-time processes, while the jump-measure integrands resist model-independent aggregation.
