Then by taking use of the method proposed by susskind and polychronakos , we gave out the non - commutative chern - simons theory to describe the incompressible quantum hall fluid on 52 and its algebraic sturcture . we also discussed the generalization of the description of the incompressile quantum hall fluid to s4 然后，利用susskind和polychronakos提出的办法，我们给出在s ~ 2上描述不可压缩量子hall流体的非对易陈- simons理论及其代数结构，同时，我们还讨论了不可压缩量子hall流体的描述在s ~ 4上的推广。
However , the long codes of random - generated ldpc are unfortunately sufferd from a defect of high encoding complexity ; especially the storage of generator matrix is considerably large during the encoding process . therefore , by way of making ldpc become realizable in the applications , it ’ s particularly important to search families of ldpc codes which may possess some algebraic structural properties 尽管如此,由于随机构造的ldpc长码在编码上有着较高的复杂度,特别是编码过程中还需要消耗大量的资源来储存生成矩阵,因此为了让ldpc码能够在实践应用中成为可行,搜寻具有一定代数结构的ldpc码就变得尤为重要。
