加权的Coxeter群_n的左胞腔(英文)

仿射Weyl群(_(2n),S)在某个群同构α(其中α(S)=S)下的固定点集合能被看作是仿射Weyl群(_n,S).那么加权的Coxeter群(_n,■)的左和双边胞腔(■是仿射Weyl群A_(2n)的长度函数),就能通过研究仿射Weyl群(_(2n),S)在群同构α下的固定点集合而给出一个清晰的划分.因此给出了加权的Coxeter群(_n,■)对应于划分k1^(2n+1-k)和(2n-1,2)的所有左胞腔的清晰刻画,这里对所有的1≤k≤2n+1.

Synthesis of trans-bis(glycin- ato) copper(II) complex nanorods by room tempera- ture solid-state reaction

One-dimensional (1D) nano materials have attractedconsiderable attention due to their broad applications inoptics, magnetism, and microsystems electronics, etc.[1,2].Different approaches have been used to prepare 1D nano-materials including vapor evaporation method[3], hydro-thermal synthesis method[4], laser ablation method[5], mi-crowave irradiation method[6], carbon nanotube-confinedtemplate method[7] and other methods. Most of these syn-thetic efforts have been focused on carbon nanotubes,…

Novel approach to synthesizing poly(propylene)-graft-poly(styrene) (PP-g-PS)

The prospected application of propylene-styrene copolymer is to be used as an additive improving the compatibility between polypropylene and polystyrene. There are already some methods applied to synthesize propylene-styrene copolymer. The first one is that propylene polymerized with sty-rene directly, catalyzed by Ziegler-Natta or metallocene catalysts. For example, TiCl4/NbClx(OR)y/MgCl2/Pb2- SiCl2/EB[1,2], TiCl3 or Cp2TiMe2/AlEt3[3] catalyst systems were reported. In these works,…
