By definition, a subset A of INxJN is P-convex iff x y z and x, z EA implies yEA. Finite P-convex sets will be called skew diagrams. A skew diagram containing the point (1, 1) will be called a diagram. X A is A-regular iff there is a P-convex set D with (1, 1) ED and X= A\D. 11 1 and 11 2 denote the natural projections JNXJN+ JN given by 1I i: For the chain {Xt 5... 5x n} we often use the short-hand notation {x,•••, x}< A B denotes the disjoint union of A and B. 1 n J
