设X_n是n条射影直线的圈,T_n是有n个穿孔的辛环。本文回顾了arxiv:1103.2462和arxiv:1109.6615中的结果,建立了一种联系X_n和T_n的同调镜像对称,并定义了T_n的纯映射类群在D^b(coh(X_N))上的作用。
Let X_n be a cycle of n projective lines, and T_n a symplectic torus with n punctures. In this paper we review results appeared in arXiv:1103.2462 and in arXiv:1109.6615, which establish a version of homological mirror symmetry relating X_n and T_n, and define on D^b(Coh(X_n)) an action of the pure mapping class group of T_n.
