... (v2+p1+p2+···+pj,v2+p1+p2+···+pj+pj+1)forj=0,1,2, ,k−1. Note that upset arcs of an upset tournament form a path,which we call its upset path.An upset tournament T with vertices v1, ,vnis in standard form pro-vided ... T= T , and thus α ∪ β is a score certificate for T .Later we will show that the bound in Theorem 2.2 is not sharp in general.The construction of score certificates for upset tournaments given in ... (vi,vj)isinT’s upset path. Thus, each Tλis in standard form, and each upset tournament can beput into standard form by relabelling its vertices.Pictorially, each upset tournament, T , in standard form...
