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
## Abstract In this paper, we show that if a 3‐connected graph __G__ other than __K__~4~ has a vertex subset __K__ that covers the set of contractible edges of __G__ and if |__K__| 3 and |__V(G)__| 3|__K__| − 1, then __K__ is a cutset of __G__. We also give examples to show that this result is best
