The paper presents results related to a theorem of Szigeti on covering symmetric skew-supermodular set functions by hypergraphs. We prove the following generalization using a variation of Schrijver's supermodular colouring theorem: if p 1 and p 2 are skew-supermodular functions with the same maximum
