Generalization of Schensted insertion algorithm to the cases of hooks and semi-shuffles

Mikhail Kogan

Given an rc-graph $R$ of permutation $w$ and an rc-graph $Y$ of permutation $v$ , we provide an insertion algorithm, which defines an rc-graph $R \leftarrow Y$ in the case when $v$ i…

RC-graphs and a generalized Littlewood-Richardson rule

M. Kogan

Using a generalization of the Schensted insertion algorithm to rc-graphs, we provide a Littlewood-Richardson rule for multiplying certain Schubert polynomials by Schur polynomials.
