Tail and free poset algebras

چکیده
We characterize free poset algebras F (P ) over partially ordered sets and show that they can be represented by upper semi-lattice algebras. Hence, the uniqueness, in decomposition into normal form, using symmetric difference, of non-zero elements of F (P ) is established. Moreover, a characterization of upper semilattice algebras that are isomorphic to free poset algebras is given in terms of a selected set of generators of B(T ).

Embedding theorems for classes of GBL-algebras
The poset product construction is used to derive embedding theorems for several classes of generalized basic logic algebras (GBL-algebras). In particular it is shown that every n-potent GBL-algebra is embedded in a poset product of finite n-potent MV-chains, and every normal GBL-algebra is embedded in a poset product of totally ordered GMV-algebras. Representable normal GBLalgebras have poset p...
متن کاملGeneralizations of Boolean products for lattice-ordered algebras
It is shown that the Boolean center of complemented elements in a bounded integral residuated lattice characterizes direct decompositions. Generalizing both Boolean products and poset sums of residuated lattices, the concepts of poset product, Priestley product and Esakia product of algebras are defined and used to prove decomposition theorems for various ordered algebras. In particular, we sho...
متن کاملPoset algebras over well quasi-ordered posets
A new class of partial order-types, class G bqo is defined and investigated here. A poset P is in the class G bqo iff the poset algebra F (P ) is generated by a better quasi-order G that is included in L(P ). The free Boolean algebra F (P ) and its free distrivutive lattice L(P ) were defined in [ABKR]. The free Boolean algebra F (P ) contains the partial order P and is generated by it: F (P ) ...
متن کاملDown-up Algebras
The algebra generated by the down and up operators on a differential partially ordered set (poset) encodes essential enumerative and structural properties of the poset. Motivated by the algebras generated by the down and up operators on posets, we introduce here a family of infinite-dimensional associative algebras called down-up algebras. We show that down-up algebras exhibit many of the impor...
متن کاملOn Posets and Hopf Algebras
We generalize the notion of the rank-generating function of a graded poset. Namely, by enumerating different chains in a poset, we can assign a quasi-symmetric function to the poset. This map is a Hopf algebra homomorphism between the reduced incidence Hopf algebra of posets and the Hopf algebra of quasi-symmetric functions. This work implies that the zeta polynomial of a poset may be viewed in...
