  Domain decomposition methods of dual-primal FETI type for edge element approximations in three dimensions

  摘要：

  We consider domain decomposition algorithms of FETI type for edge element approximations in three dimensions. We first show that a strong coupling exists between tangential degrees of freedom associated to the subdomain edges and faces. We then propose a dual-primal FETI algorithm that relies on a change of basis and on a suitable choice of a coarse space. We give a logarithmic bound for the condition number of the resulting preconditioned operator. Numerical results confirm this bound and the necessity of performing a change of basis.

  日期：2003.11

  Penta- and octasaccharides composed of β-(1→6)-linked galactose backbone with α-(1→2)-linked arabinose branches were synthesized through coupling of α-(1→5)-linked arabinofuranosyl disaccharide donor with a tri- and tetrasaccharide backbone at C-2, respectively.

  通过将α-（1→5）连接的阿拉伯呋喃糖基二糖供体与三-α-（1→5）连接的阿拉伯呋喃糖基二糖供体偶联，合成由β-（1→6）连接的半乳​​糖骨架和α-（1→2）连接的阿拉伯糖支组成的五糖和八糖。 C-2分别为四糖主链和四糖主链。
