... in the graph a t the time. To analyse the effect of prioritisation, we consider the effect of an operation Op on a set V i as the simultaneous destruction of some vertices of V i (by deleting them ... duality theorem of linear programming then gives us a simple way to check the claimed upper bound on the solution given by the primal LP. One of the themes of...

(Here and subsequently, the notation (a, b) ∈ S P serves as a convenient shorthand for the condition that a and b are (possibly empty) words on disjoint sets of letters ... x i ) ∈ C be the slope of ℓ ij . Let A = C[m ij ], and let I n ⊂ A be the ideal of algebraic relations on the slopes m ij that hold for all choices of the p...

... sequence of nonempty, closed, and convex subsets of the weakly compact and convex set coC. The ˇ Smulian theorem [6, Theorem V.6.2] then allows us to conclude that A ∞ is nonempty. Conversely, ... {C n } ∞ n=1 of nonempty, closed, and convex subsets of the bounded and convex set coC, then µ(C n ) = 0 (n ∈ N), and therefore C ∞ = ∅. Appealing again to the ˇ Smulian t...
