中文摘要:
      对于$\Pi_{1}$空间上$J$-正常算子的$J$-酉等价问题进行讨论. 针对不同情况, 给出了$\Pi_{1}$空间上两个$J$-正常算子$J$-酉等价的充要条件. 这将有助于研究$\Pi_{1}$空间上交换$J$-von Neumann代数之间的$J$-酉等价.
英文摘要:
      $J$-unitary equivalence of $J$-normal operators on $\Pi_{1}$ space is discussed. The authors get necessary and sufficient conditions for the $J$-unitary equivalence of two $J$-normal operators on $\Pi_{1}$ space. It will be useful to the discussion about $J$-unitary equivalence of commutative $J$-von Neumann algebras on $\Pi_{1}$ space.
