Hyperinvariant, characteristic and marked subspaces

Pudji Astuti, Harald K. Wimmer

Let $V$ be a finite dimensional vector space over a field $K$ and $f$ a $K$ -endomorphism of $V$ . In this paper we study three types of $f$ -invariant subspaces, namely hyperinvarian…

Characteristic and hyperinvariant subspaces over the field GF(2)

Pudji Astuti, Harald K. Wimmer

Let $f$ be an endomorphism of a vector space $V$ over a field $K$ . An $f$ -invariant subspace $X \subseteq V$ is called hyperinvariant (respectively characteristic) if $X$ is invari…

Characteristic subspaces and hyperinvariant frames

Pudji Astuti, Harald K. Wimmer

Let $f$ be an endomorphism of a finite dimensional vector space $V$ over a field $K$ . An $f$ -invariant subspace of $V$ is called hyperinvariant (respectively characteristic) if it…
