AbstractIn the first lecture I will give an introduction to the notion of a Henselian local ring, i.e. a local ring satisfying Hensel's property. Examples are the rings of p-adic integers and formal power series over a field. At the same time I will review several important morphisms in algebraic geometry that rely on Hensel rings, especially quasi-finite and {\'e}tale morphisms. In the second ...
AbstractIn the last talk, we introduced some basic concepts of symmetry group which is used to describe the symmetry of sets or differential equation. In this talk, we will continue to present the application of finding invariant solution and linearization.Speaker IntroXiaopei Jiao obtained the B.S. degree from Shanghai Jiao Tong University in 2017 and Ph.D. degree from Department of Mathematic...
