epimorphisms of incidence structures; unions of substructures; incidence structure (context) and its special cases: complete, open, trivial, regular, simple, modular; onto homomorphisms of incidence structures; union of substructures: disjoint, complete
Summary:
Some decompositions of general incidence structures with regard to distinguished components (modular or simple) are considered and several structure theorems for them are deduced.
