Abstract Strata of meromorphic $1$-forms are endowed with the atlas of period coordinates given by the periods of the differential on arcs joining the $n$ zeroes of the differential. Fixing
数学科学年终盛会 2022年12月22日—29日，数学科学前沿大会将于海南省清华三亚国际数学论坛举行，聚焦纯数学与应用数学前沿领域方方面面。 2018年菲尔兹奖得主Caucher Birkar、2006年菲尔兹奖得主Andrei Okounkov...
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

Abstract This talk will focus on the mathematical concept so-called A-polynomial, which characterize the knot complement from an algebraic viewpoint. I will discuss the classical A-polynomial and i...
