Quantifier Elimination and Other Model-Theoretic Properties of BL-Algebras

open access: yesNotre Dame Journal of Formal Logic, 2011
This work presents a model-theoretic approach to the study of firstorder theories of classes of BL-chains. Among other facts, we present several classes of BL-algebras, generating the whole variety of BL-algebras whose firstorder theory has quantifier elimination. Model-completeness and decision problems are also investigated.

DMA:an algebra for multicriteria spatial modeling [PDF]

open access: yes, 2006
The objective of this paper is to propose a new algebra, called decision map algebra (DMA), especially devoted to multicriteria spatial modeling. DMA is a generic and context-independent modeling language inspired from map algebra and other similar ...

The property of independence for Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
The studies carried out in this article are connected with the description of model - theoretic properties of some, generally speaking, incomplete classes of theories that make a subclass of inductive theories.

A Cartan-Eilenberg approach to Homotopical Algebra [PDF]

open access: yes, 2010
In this paper we propose an approach to homotopical algebra where the basic ingredient is a category with two classes of distinguished morphisms: strong and weak equivalences.

Probabilistic Programming Process Algebra [PDF]

open access: yes, 2014
Formal modelling languages such as process algebras are widespread and effective tools in computational modelling. However, handling data and uncertainty in a statistically meaningful way is an open problem in formal modelling, severely hampering the ...

Thermalization in quenched open quantum cosmology

open access: yesNuclear Physics B, 2023
In this article, we study the quantum field theoretic generalization of the Caldeira-Leggett model in general curved space-time considering interactions between two scalar fields in a classical gravitational background.

Criterion for the cosemanticness of the Abelian groups in the enriched signature

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
In the present paper we give a criterion of the cosemanticness relative to the Jonsson spectrum of the model in the class of Abelian groups with a distinguished predicate.

Superuniversality of Superdiffusion

open access: yesPhysical Review X, 2021
Anomalous finite-temperature transport has recently been observed in numerical studies of various integrable models in one dimension; these models share the feature of being invariant under a continuous non-Abelian global symmetry.

A Verified Algebra for Linked Data [PDF]

open access: yes, 2011
A foundation is investigated for the application of loosely structured data on the Web. This area is often referred to as Linked Data, due to the use of URIs in data to establish links.

Model-theoretic Forcing in Transition Algebra

open access: yesCoRR
We study Löwenheim-Skolem and Omitting Types theorems in Transition Algebra, a logical system obtained by enhancing many sorted first-order logic with features from dynamic logic. The sentences we consider include compositions, unions, and transitive closures of transition relations, which are treated similarly to actions in dynamic logics to define ...
