For a graph G whose vertices are vl, u2, . . . , v, and where E is the set of edges, we define a functional U,(h)= ss SC . . . frl,$EEh(Xi,Xj) > dPc(x~)dAxJ ... dp(x,), where h is a nonnegative symmetric function of two variables. We consider a binary relation + for graphs with fixed numbers of vert
Two general kinds of subsets of a partially ordered set P are always retracts of P:: (1) every maximal chain of P is a retract; (2) in P, every isometric, spanning subset of length one with no crowns is a retract. It follows that in a partially ordered set P with the fixed point property, every maxi
