    • S(H)上保*-同构的线性映射(英文) 

      冯文文; 杜拴平; 侯晋川 (2016-03-30)
      本文讨论了S(H)上保*-同构的线性映射.主要结论为:令H是复的有限维希尔伯特空间.我们记B(H)为H上的所有有界线性算子构成的Banach代数、S(H)为H上的所有自伴算子构成的实线性子空间,则有:为S(H)到S(H)的双边保*-同构的有界线性满射当且仅当存在B(H)上的可逆元A使得对所有T∈S(H)有(T)=ATA*.

    • Second order asymptotics for ruin probabilities in a renewal risk model with heavy-tailed claims 

      Lin, Jianxi; 林建希 (INSUR MATH ECON, 2012-09)
      In this paper, we establish the second order asymptotics of ruin probabilities of a renewal risk model under the condition that the equilibrium distribution of claim sizes belongs to a rather general heavy-tailed distribution ...

    • SEFP:一种新的固定度为4的Cayley互连网络 

      陈宝兴; 肖文俊 (2002-09-25)
      提出一种新的固定度为4的正则互连网络SEFPn,它是一种置换群Sn上的Cayley 图。SEFPn是基于洗牌(shuffle),交换(exchange)及翻转(flip)运算的互连网络。它直径短,其直径大约是SEPn(洗牌交换置换网络[5])的一半。我们提出了基于此网络的路由算法,并由此得到了此网络的直径估计。这种网络被证明能有效模拟其它基于置换群Sn上的Cayley 图。在要求具有限定数量的I/O端口的VLSI实现方面,此网络很具有吸 ...
