AbstractIn this talk I will introduce how Prof. Birkar's construction of compact moduli spaces of stable minimal models is used to give a generalization of Shafarevich's program to higher dimensional families with fibers of an arbitrary Kodaira dimension
摘 要:Topological orders are gapped quantum liquid states without any symmetry. Most of their properties can be captured by investigating topological defects and excitations of various dimensions. Topological defects in n dimensions naturally form a (weak) n-category. In particular, anomalous topological order (boundary theory) is described by fusion n-category and anomaly-free topological ord...
