Description

to ribbon
Description
The ribbon shape corresponding to an integer composition.
For an integer composition (a1,…,an), this is the ribbon shape whose ith row from the bottom has ai cells.
For an integer composition (a1,…,an), this is the ribbon shape whose ith row from the bottom has ai cells.

dominating sublattice
Description
Return the sublattice of the dominance order induced by the support of the expansion of the skew Schur function into Schur functions.
Consider the expansion of the skew Schur function sλ/μ=∑νcλμ,νsν as a linear combination of straight Schur functions.
It is shown in [1] that the subposet of the dominance order whose elements are the partitions ν with cλμ,ν>0 form a lattice.
The example λ=(52,42,1) and μ=(3,2) shows that this lattice is not a sublattice of the dominance order.
