From Separation Logic to First-Order Logic
Separation logic is a spatial logic for reasoning locally about heap structures. A decidable fragment of its assertion language was presented in [1], based on a bounded model property. We exploit this property to give an encoding of this fragment into a first-order logic containing only the propositional connectives, quantification over the natural numbers and equality. This result is the first...
متن کاملFrom first order logic to Nd: a data driven reformulation
First order logic FOL ooers a natural way o f modeling domains such as chemistry: a molecule is most adequately described as a graph of atoms linked by simple or double bonds. To o vercome the speciic diiculties of dealing with FOL, this paper presents an automatic mapping from the initial problem domain onto the set of integer vectors IN d , where d is a user-supplied integer. This mapping ont...
متن کاملBeyond First Order Logic: From number of structures to structure of numbers: Part I
We study the history and recent developments in nonelementarymodel theory focusing on the framework of abstractelementary classes. We discuss the role of syntax and semanticsand the motivation to generalize first order model theory to nonelementaryframeworks and illuminate the study with concrete examplesof classes of models. This first part introduces the main conceps and philosophies anddiscu...

متن کاملUsing First-Order Logic to Query Heterogeneous Internet Data Sources
This paper describes an approach to formulate queries in the language of first order logic over data from disparate sources distributed over a network. The data sources are treated as if they were all in a common database. The data sources may incorporate different stored or computed methods of providing data– web services and REST APIs, XML/JSON repositories, web pages, full featured databases...
