Combinatorial Order Theory, properties present in any poset, such as chains, antichains, matchings, etc. Typical problems to be considered are the determination of the minimal number of chains into which a finite poset can be decomposed or the existence of a matching between the points and copoints of a ranked poset. In fact,

Incidence Functions,ions and inversion formulae in an arbitrary poset. Our method of study will be to associate with the poset . an algebraic object called the incidence algebra . (.), and to investigate its structure and subobjects.
