| Abstract: | We study the properties of continuous homomorphisms from β S into N
*
and from N
*
into N
*
. We show that the image C of N
*
under a continuous homomorphism which does not arise from the continuous extension of a homomorphism mapping N to itself, has the property that C+C is a singleton. |
