چکیده

We generalize the main result of [K–K–S] concerning the convex embeddings of a chain Γ in a lexicographic power ∆Γ. For a fixed non-empty chain ∆, we derive necessary and sufficient conditions for the existence of non-empty solutions Γ to each of the lexicographic functorial equations (∆) ' Γ , (∆) ' Γ and (∆) ' Γ .

Functional Equations for Lexicographic Products *

We generalize the main result of [K–K–S] concerning the convex embeddings of a chain Γ in a lexicographic power ∆Γ. For a fixed non-empty chain ∆, we derive necessary and sufficient conditions for the existence of non-empty solutions Γ to each of the lexicographic functional equations (∆) ≃ Γ , (∆) ≃ Γ and (∆) ≃ Γ .

On Lexicographic Products of Two Fuzzy Graphs

Abstract. In this paper, lexicographic products of two fuzzy graphs namely, lexicographic min-product and lexicographic max-product which are analogous to the concept lexicographic product in crisp graph theory are defined. It is illustrated that the operations lexicographic products are not commutative. The connected, effective and complete properties of the operations lexicographic products a...

Solutions of Functorial and Non-functorial Metric Domain Equations 1

A new method for solving domain equations in categories of metric spaces is studied. The categories CMS and KMS are introduced, having complete and compact metric spaces as objects and-adjoint pairs as arrows. The existence and uniqueness of xed points for certain endofunctors on these categories is established. The classes of complete and compact metric spaces are considered as pseudo-metric s...

Counting and Gröbner Bases

Gröbner bases were introduced by Buchberger (1965) and are now firmly established as a tool in Commutative Algebra and other areas. The reader is referred to Buchberger (1985), Cox, Little and O’Shea (1992) or Becker and Weispfenning (1993) for more information. Eisenbud (1995) places Gröbner bases within the context of more advanced Commutative Algebra. The ingredients for a Gröbner basis are ...
