An involution for symmetry of hook length and part length of pointed partitions

A pointed partition   of nn is a pair (λ,v)(λ,v), where λλ is a partition of nn and vv is a cell in its Ferrers diagram. In this paper, an involution on pointed partitions of nn exchanging hook length and part length is constructed. This gives a bijective proof of a recent result of Bessenrodt and Han (2009) [4].
