Description

Integer partitions λ ⊢ n are combinatorial objects with well known

applications in other areas of mathematics. A map on the set of partitions

of a given n ≥ 2 is known to partially determine the structure of important

representations of the symmetric group Sn; the group of permutations of n

elements. In this talk we will introduce generalisations of this map and explore

their combinatorial properties.
