A new type of cold spray coating, made from the metal tantalum and applied to the plasma-facing steel walls of fusion reactors, could lead to efficient, compact fusion reactors that are easy to repair...
On a smooth compact manifold of dimensions three and four with totally non-umbilic boundary,imposing non-negativity assumptions on curvatures of the background metric, we establish that there exists a...
Using the results presented in the previous lecture, namely the generalization of the Tsirelson's theorem [2] to mixed volumes, we calculate the mixed volume of the closed convex hulls of the two orth...
Let K be a convex compact subset of a separable Hilbert space H. One of the most important geometric characteristics of K is its intrinsic volumes. In the finitedimensionalcase (K ? R^d), the intrinsi...
In this talk, we shall review firstly the study history of Kazdan-Warner equations on compact Riemann surfaces, which was proposed by Kazdan and Warner on Annals of Math on 1974. Then we shall show th...
CERN and INFN have developed a compact, transportable accelerator for the non-destructive analysis of historical artifacts and artworks, providing a cheaper, more accessible method of analysing large ...
We single out a notion of staticity which applies to any domain in hyperbolic space whose boundary is a non-compact totally umbilical hypersurface. For (time-symmetric) initial data sets modeled at in...
近年来,量子计算机技术发展迅速,它对传统公钥密码算法的安全性带来了潜在的巨大威胁。因此,美国、中国、欧盟等世界主要国家和地区纷纷开始研制抗量子计算机攻击的密码算法。其中,美国国家标准与技术研究院(National Institute of Standards and Technology,NIST)于2016年面向全球征集抗量子密码算法标准,并于2017年底完成了首轮候选算法的征集工作。
On the deformation theory of represen tations of fundamen talgroups of compact hyprbolic 3-manifolds.
We prove results toward classifying compact Lorentz manifolds on which Heisenberg groups act isometrically. We give a general construction, leading to a new example, of codimension-one actions—those...
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...
We present a new third-order central scheme for approximating solutions of systems of conservation laws in one and two space dimensions. In the spirit of Godunov-type schemes, our method is based on r...
We study compact group extensions of hyperbolic diffeomorphisms. We relate mixing properties of such extensions with accessibility properties of their stable and unstable laminations. We show that g...
We show that a smooth compact Riemannian manifold of dimension  2 admits a Bernoulli di eomorphism with nonzero Lyapunov exponents.
Recently several new phenomena in dynamics were discovered by looking at small perturbations of compact group extensions of hypebolic systems [8, 14]. In view of this it is desirable to develop a gen...
