半闭域上矩阵代数的交换子空间的刻划

THE CHARACTERISTICS OF THE COMMUTATOR SPACE OF MATRIX ALGEBRA OVER A SEMI CLOSED FIELD

本文通过半闭域上矩阵相似的标准形。

By using the canonical matrix which is similar to a matrix over semi closed field this paper,arrives at the conclusion that commutator space coincides with its zero trace space,which is the same as over closed field.
