摘要
定义了一种谱分布并讨论了这种谱分布的性质 ,证明了闭算子A为某k阶谱分布的矩量的充要条件是iA生成某k阶分布群 ,此时12 (iA) 2
A kind of spectral distribution and its properties are introduced. It is proved that A , a closed operator, is the momentum of spectral distribution of order k iff i A generate a smooth distribution semigroup of order k ; in this case12(i A ) 2 generates a regular semigroup.
