Normal sets and their order-automorphisms
Abstract
For a finite set X and the prower set 
of X, we definite normal subsets of . We then describe all order-automorphisms of a normal subset of , and, in particular, characterize those normal subsets of for which each order-automorphism is induced, i. e. determined by a permutation of X.
