Fixed Points of Products and Ordered Sums of Simply Ordered Sets

Let A and B be simply ordered sets and A XB the cartesian product ordered by first differences. Sufficiency conditions are given on the sets A and B for the existence of fixed points in the set AXB (Theorem 2). Sufficiency conditions are given on the sets A, B, and C for the incomparability of the order types1 \A XB\ and \A XC\ (| CXA\ and | CXB\) (Corollary 2 of Theorem 7). The content of Theo...

On Finite Simply Reducible Groups

A finite group G is said to be simply reducible (SR-group) if it has the following two properties: 1) each element of G is conjugate to its inverse; 2) the tensor product of every two irreducible representations is decomposed as a sum of irreducible representations of G with multiplicities not exceeding 1. It is proved that a finite SR-group is solvable if it has no composition factors isomorph...

On Ordered Polycyclic Groups

It has been asserted that any (full) order on a torsion-free, finitely generated, nilpotent group is defined by some F-basis of G and that the group of o-automorphisms of such a group is itself a group of the same kind: Examples provided herein demonstrate that both of these assertions are false; however, it is proved that the group of o-automorphisms of an ordered, polycyclic group is nilpoten...

On Sums Over Partially Ordered Sets

We establish a general theorem for reducing sums of type ∑ y≥x g(y) where g is a mapping from a partially ordered set into an abelian group. Conclusions concern the Möbius function, the principle of inclusionexclusion, the Tutte polynomial and Crapo’s beta invariant.
