Operations on Arc Diagrams and Degenerations for Invariant Subspaces of Linear Operators. Part II

Mariusz Kaniecki, Justyna Kosakowska, Markus Schmidmeier

For a partition $\beta$, denote by $N_{\beta }$ the nilpotent linear operator of Jordan type $\beta$. Given partitions $\beta$, $\gamma$, we investigate the representation space ${}_2{\mathbb{V}}_{\gamma }^{\beta }$ of a…
