Query: Reflected BSDE driven by G-Brownian motion with an upper obstacle   In this paper, we study the reflected backward stochastic differential
equation driven by G-Brownian motion (reflected G-BSDE for short) with an upper
obstacle. The existence is proved by approximation via penalization. By using a
variant comparison theorem, we show that the solution we constructed is the
largest one.
