Abstract:We extend the study of brane quantization via SYZ mirror symmetry to the setting of singular fibers, building on recent joint work with Chan, Leung, and Li in the semi-flat case. We consider a crepant resolution $X\to\mathbb{C}^2/\mathbb{Z}_{n+1}$ of the $A_n$-singularity, whose mirror $\check{X}$ is also realized as a resolution of $\mathbb{C}^2/\mathbb{Z}_{n+1}$. For each level $k\in\mathbb{Z}_{>0}$, we construct a space filling coisotropic A-brane $\mathcal{B}_{cc}^{(k)}$ of $(X,k\omega)$ and determine its mirror B-brane $\check{\mathcal{B}}_{cc}^{(k)}$ via fiberwise geometric quantization. We then define the endomorphism algebra $Hom_A(\mathcal{B}_{cc}^{(k)},\mathcal{B}_{cc}^{(k)})$ by gluing analytic quantum tori using wall-crossing formulas and establish a mirror isomorphism $Hom_A(\mathcal{B}_{cc}^{(k)},\mathcal{B}_{cc}^{(k)})\cong Hom_B(\check{\mathcal{B}}_{cc}^{(k)},\check{\mathcal{B}}_{cc}^{(k)})$.
