On Numerical Counting of Prime,UPO, and the General Type of Posets According To Heights

Khamis, Soheir 


Abstract


This paper gives numerical values of non-isomorphic Prime, UPO, and the general types of posets with n elements (n≤ 12) according to heights. These countings depend on two aspects: First one is the modification of the algorithms in [l] and [6]. The second is to apply a technique which gives the general forms for the relations between the generating functions of two arguments, viz. the cardinality of a poset ad its height, for non-isomorphic essentially series, essentially parallel, and (+,⨁)-irreducible posets.
