The skew diagram poset and components of skew characters
Christian Gutschwager
We investigate the poset of skew diagrams ordered by adding or forming the union of skew diagrams. We will show that a skew diagram which has at least n convex corners to the upper…
Skew characters which contain only few components
Christian Gutschwager
Wrong assumptions were made in the proof of Theorem 3.12 and Lemma 3.6. A preprint containing a correct proof for Lemma 3.6 is in preparation and will be uploaded later this month.…
Reduced Kronecker products which are multiplicity free or contain only few components
Christian Gutschwager
It is known that the Kronecker coefficient of three partitions is a bounded and weakly increasing sequence if one increases the first part of all three partitions. Furthermore if t…
Generalised Stretched Littlewood-Richardson Coefficients
Christian Gutschwager
The Littlewood-Richardson (LR) coefficient counts among many other things the LR tableaux of a given shape and a given content. We prove, that the number of LR tableaux weakly incr…
Equality of multiplicity free skew characters
Christian Gutschwager
In this paper we show that two skew diagrams lambda/mu and alpha/beta can represent the same multiplicity free skew character [lambda/mu]=[alpha/beta] only in the the trivial cases…
On Base Partitions And Cover Partitions Of Skew Characters
Christian Gutschwager
In this paper we give an easy combinatorial description for the base partition B of a skew character [A], which is the intersection of all partitions alpha whose corresponding char…
