非奇异矩阵的奇异线性变换

The singular linear preservers of non-singular matrices

Clément de Seguins Pazzis

摘要:

给定任意域K,我们将M_n(K)中稳定GL_n(K)的奇异自同态$f$的确定归结为K上n维除代数的分类.我们的方法基于M_n(K)的奇异子空间的Dieudonne定理,也给出了经典非奇异情形的一个证明.

英文摘要:

Given an arbitrary field K, we reduce the determination of the singular endomorphisms $f$ of M_n(K) that stabilize GL_n(K) to the classification of n-dimensional division algebras over K. Our method, which is based upon Dieudonné's theorem on singular subspaces of M_n(K), also yields a proof for the classical non-singular case.
