Maximal supports and Schur-positivity among connected skew shapes
Peter R. W. McNamara, Stephanie van Willigenburg
The Schur-positivity order on skew shapes is defined by B \leq A if the difference s_A - s_B is Schur-positive. It is an open problem to determine those connected skew shapes that…
Multiplicity free Schur, skew Schur, and quasisymmetric Schur functions
Christine Bessenrodt, Stephanie van Willigenburg
In this paper we classify all Schur functions and skew Schur functions that are multiplicity free when expanded in the basis of fundamental quasisymmetric functions, termed F-multi…
On (almost) extreme components in Kronecker products of characters of the symmetric groups
Christine Bessenrodt, Stephanie van Willigenburg
Using a recursion formula due to Dvir, we obtain information on maximal and almost maximal components in Kronecker products of characters of the symmetric groups. This is applied t…
