In this talk, we talk about the proof of the O(2)-symmetry of 3D steady gradient solitons. The proof consists of four parts: the asymptotic analysis at infinity, the symmetry improvement theorem, the ...
In this talk, we will study the residual Monge-Ampère mass of a plurisubharmonic function with isolated singularity at the origin in C2. We proved that the residual mass is zero if its Lelong number i...
In 1974, Jeffrey Rauch proposed the hot spot conjecture for the second eigenfunctions of the Neumann eigenvalue problems. We will recall some of its development and related studies in recent years. We...
Cayley graphs form an important class of vertex-transitive graphs, which have been the object of study for many decades. These graphs admit a group of automorphisms that acts regularly (sharply-transi...
近日,中国科学技术大学物理学院北京谱仪BESIII研究团队在Symmetry期刊发表专辑,总结了以中国科学技术大学物理学院师生为主、国内外多家单位参加的重子内部结构方面的系列成果。该专辑收录9篇论文,其中概要1篇、理论综述1篇,以BESIII结果为基础的实验综述7篇。
Physicists and engineers have long been interested in creating new forms of matter, those not typically found in nature. Such materials might find use someday in, for example, novel computer chips. Be...
Engineers and scientists at The University of Texas at Austin and the AMOLF institute in the Netherlands have invented the first mechanical metamaterials that easily transfer motion effortlessly in on...
Ultrafast excited state energy transfer to the primary electron donor or special pair in photosynthetic reaction centers has been measured following excitation of the lowest electronic state of the ot...
A 51 bp section of the Rhodobacter capsulatus photosynthetic reaction center M subunit gene (nucleotides M562-M612 of the pufM structural sequence) encoding amino acids M187-M203 was replaced by the h...
The orientation preserving topological symmetry group of a graph embedded in the 3-sphere is the subgroup of the automorphism group of the graph consisting of those automorphisms which can be induc...
We prove that for every closed, connected, orientable, irreducible 3-manifold, there exists an alternating group An which is not the topological symmetry group of any graph embedded in the manifold. ...
We prove a structure theorem for compact aspherical Lorentz manifolds with abundant local symmetry. If M is a compact, aspherical, real-analytic, complete Lorentz manifold such that the isometry grou...
This paper is a commentary on the experimental observation observa- tions of Bensimon et al. [1] of convection of a binary uid mixture in a uid annulus. They observed a convective pattern that is ...
