首先接触到核(kernel)这个概念,还是早在学习离散数学的时候,同态的核。 同态的核指的是同态映射中,映射到同态的象集中的单位元的原象的集合。(抱歉说得这么绕) 当时就不懂为啥这玩意要叫核。凭啥它就叫核了呢?这个核有什么用呢?因为当时学得并不深入,所以这些疑问不了了之。 后来这学期学了一点抽象代数,才...

What does “Kernel” mean/imply?What does “Kernel” mean/imply? Since I don’t know that is, many of the comments had no meaning for me. BTW, I earned my Ph.D. in 1974 in Computer Psychology. Today it would have been called AI. It now is a very different computer world....
A finite group is said to be a Frobenius group if there is a non-trivial subgroup of (known as the Frobenius complement of ) such that the conjugates of are “disjoint as possible” in the sense that whenever . This gives a decomposition where the Frobenius kernel of is defined as the...
