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...
课程描述 DescriptionCategorical dynamical systems have fruitful connections with various mathematical fields, for instance with algebraic geometry, Teichmuller theory, symplectic geometry, and dynamical systems. The goal of this course is to give an introduction to the recent works on categorical dynamical systems. We will discuss topics that are closely related to the development of categorica...
