M_2(F_2)的保幂等加法算子

Additive Operators of 2×2 Matrix Space are the Field F 2 with|F 2|=2 Preserving Idempotence

刻划了Ｆ２（两个元素的域）上全矩阵加法群Ｍ２（Ｆ２）的保幂等自同态，得到几类非标准形式。

The author characterizes additive operators of 2×2 Matrix Space over the field F 2 with |F 2|=2 presrving idernpitence, and obtains some nonstandard forms.
