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

The average height of an element x in a finite poset P is the expected number of elements below x in a random linear extension of P. We prove a number of theorems about average height, some intuitive and some not, using a recent result of L.A. Shepp. Let P be an arbitrary finite poset having n elem
## L dimension may be chosen within each of the subspaces L in the set S that are ''in general position.'' For example, in the real projective space of dimension 3, consider a plane , a line r not belonging to , the point P [ r l , and two distinct points Q, R both different from P, lying on the l
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
