| 摘 要： | Fock空间是由整函数组成的具有再生核的Hilbert空间.Fock空间上的乘法算子的定义域不是整个Fock空间,它在Fock空间上是稠定的.研究了Fock空间上的乘法算子的性质,对其值域进行了刻画,并得出了乘法算子作用在Fock空间的拟不变子空间上值域余一维的充要条件.

| Abstract: | Fock space is a reproducing Hilbert space which consists of entire functions. Multiplication operators are densely defined on the Fock space,not on whole space.This paper studies multiplication operators on the Fock space,we character the range of multiplication operators and obtain a necessary and sufficient condition for multiplication operators on quasi- invariant subspaces to be codimension one. |

| Keywords: | Fock space multiplication operators quasi-invariant subspaces |
