Theory of Demi-Group Structures, II: Uniform Demi Groups and Duality

The first part of the paper [6] dealt with relations between structure theorems of various types for d-structures, that is commutative (additive) demi-groups with zero element with a superposed structure (order-based, topological or uniform structure usually) when the composite structure satisfies certain axioms regarding a type of mapping called d-homomorphism.
