Neat embeddings as adjoint situations
نویسنده
چکیده
Looking at the operation of forming neat α-reducts as a functor, with α an infinite ordinal, we investigate when such a functor obtained by truncating ω dimensions, has a right adjoint. We show that the neat reduct functor for representable cylindric algebras does not have a right adjoint, while that of polyadic algebras is an equivalence. We relate this categorical result to several amalgamation properties for classes of representable algebras. 1

Neat Embedding Is Not Sufficient for Complete Representability
In [4] we characterize the class of countable completey representable relation and cylindric algebras via special neat embeddings. In this note we provide a counterexample showing that the condition of countability cannot be omitted.
متن کاملAdding flavour to the Polchinski-Strassler background
As an extension of holography with flavour, we analyze in detail the embedding of a D7-brane probe into the Polchinski-Strassler gravity background, in which the breaking of conformal symmetry is induced by a 3-form flux G3. This corresponds to giving masses to the adjoint chiral multiplets. We consider the N = 2 supersymmetric case in which one of the adjoint chiral multiplets is kept massless...
متن کاملAdjoint Line Bundles and Syzygies of Projective Varieties
Let X be a smooth projective variety and let K be the canonical divisor of X. In this paper, we study embeddings of X given by adjoint line bundles K ⊗ L, where L is an ample invertible sheaf. When X is a regular surface, we obtain a numerical criterion for K ⊗ L to have property Np. In particular, we prove Mukai’s conjecture for regular anticanonical surfaces. When X is a regular variety of ar...
متن کاملNeat Embeddings and Amalgamation
We present a property of neat reducts commuting with forming subalgebras as a definability condition. The purpose of this paper is to relate results on neat reducts, a notion particular to cylindric algebras to results on the “more universal” strong amalgamation property in a very general setting. It is known [7], [8] and [6] that amalgamation properties in a class of algebras correspond to int...
متن کاملHecke Operators and Q-groups Associated to Self-adjoint Homogeneous Cones
Let G be a reductive algebraic group associated to a self-adjoint homogeneous cone defined over Q, and let Γ ⊂ G be a appropriate neat arithmetic subgroup. We present two algorithms to compute the action of the Hecke operators on H(Γ;Z) for all i. This simultaneously generalizes the modular symbol algorithm of Ash-Rudolph [7] to a larger class of groups, and provides techniques to compute the H...
