The lattice of characteristic subspaces of an endomorphism with Jordan-Chevalley decomposition

摘要: Given an endomorphism A over a finite dimensional vector space having Jordan-Chevalley decomposition, the lattices of invariant and hyperinvariant subspaces can be obtained from nilpotent part this decomposition. We extend result for characteristic subspaces. also obtain generalization Shoda's Theorem about characterization existence non
