Abstract Quasitriangular Hopf algebras are Hopf algebras whose finite-dimensional representations form braided rigid tensor categories, which are naturally related thto low-dimensional topology.
Abstract We consider a closed oriented surface of genus at least 2. To describe curves on it, one natural idea is to choose once for all a collection of curves as a reference system and to hope
Abstract The second Chern class $c_2$ plays a special role in studying Calabi-Yau threefolds. Among other things, we discuss about KSC (Kawaguchi-Silverman's Conjecture) and the finiteness problem
Abstract Recent years have witnessed an explosion of studies of the non-invertible symmetries in various dimensions. In this talk, I will revisit the most vanilla type of non-invertible symmetry
Abstract We use the machinery of A1-homotopy theory to study the geometric ramification theory. We define the quadratic Artin conductor for a motivic spectrum on a smooth proper curve and obtain
