Dual Ramsey properties for classes of algebras

نویسندگان

چکیده

Almost any reasonable class of finite relational structures has the Ramsey property or a precompact expansion. In contrast to that, list classes algebras with expansion is surprisingly short. this paper we show that nontrivial variety (that is, equationally defined algebras) enjoys various dual properties. We develop completely new set strategies rely on fact left adjoints preserve property, and then treat as Eilenberg–Moore categories for monad. in have small degrees, every algebra big degree free countably many generators. As usual, these come consequences ordered versions statements.

Ramsey Properties for Classes of Relational Systems

1. Ramsey properties of categories were introduced in [5,9]. Here we study it for the categories of relational systems (of the same type) whose morphisms are embeddings. A weaker notion, namely the vertex partition property for relational systems has been studied in [12]. The paper is closely related to Jezek and Nesetnl's paper [8] in the sense that most of the constructions are more or less s...

Splittings and Ramsey Properties of Permutation Classes

We say that a permutation π is merged from permutations ρ and τ , if we can color the elements of π red and blue so that the red elements are order-isomorphic to ρ and the blue ones to τ . A permutation class is a set of permutations closed under taking subpermutations. A permutation class C is splittable if it has two proper subclasses A and B such that every element of C can be obtained by me...

On Ramsey properties of classes with forbidden trees

Let F be a set of relational trees and let Forbh(F ) be the class of all structures that admit no homomorphism from any tree in F ; all this happens over a fixed finite relational signature σ. There is a natural way to expand Forbh(F ) by unary relations to an amalgamation class. This expanded class, enhanced with a linear ordering, has the Ramsey property.

Dual Ramsey Theorem for Trees

The classical Ramsey theorem was generalized in two major ways: to the dual Ramsey theorem, by Graham and Rothschild, and to Ramsey theorems for trees, initially by Deuber and Leeb. Bringing these two lines of thought together, we prove the dual Ramsey theorem for trees. Galois connections between partial orders are used in formulating this theorem, while the abstract approach to Ramsey theory,...
