The existence of Hall polynomials for $x^{2}$ -bounded invariant subspaces of nilpotent linear operators

Stanisław Kasjan, Justyna Kosakowska

We prove the existence of Hall polynomials for $x^{2}$ -bounded invariant subspaces of nilpotent linear operators.

The socle tableau as a dual version of the Littlewood-Richardson tableau

Justyna Kosakowska, Markus Schmidmeier

Like the LR-tableau, a socle tableau is given as a skew diagram with certain entries. Unlike in the LR-tableau, the entries in the socle tableau are weakly increasing in each row,…

Combinatorial algorithms for binary operations on LR-tableaux with entries equal to 1 with applications to nilpotent linear operators

Mariusz Kaniecki, Justyna Kosakowska

In the paper we investigate an algorithmic associative binary operation $*$ on the set $L R_{1}$ of Littlewood-Richardson tableaux with entries equal to one. We extend $*$ t…
