Ruan's conjecture on orbifold symplectic flops

Let $X$ and $Y$ be orbifolds related by an orbifold symplectic flop. The orbifold quantum cohomology rings are denoted by $QH^\ast_{CR}(X)$ and $QH^\ast_{CR}(Y)$. Ruan's conjecture. If $Y$ is the orbifold symplectic flop of $X$, then

$$QH^\ast_{CR}(X)\cong QH^\ast_{CR}(Y).$$

This conjecture asks whether orbifold quantum cohomology is invariant under orbifold symplectic flops, extending the corresponding transformation result for smooth flops. The source presents it as a proposed analogue of Ruan's conjecture; its resolution is not specified here.
