Logical Frameworks--A Brief Introduction
نویسنده
چکیده
A logical framework is a meta-language for the formalization of deductive systems. We provide a brief introduction to logical frameworks and their methodology, concentrating on LF. We use first-order logic as the running example to illustrate the representations of syntax, natural deductions, and proof transformations. We also sketch a recent formulation of LF centered on the notion of canonical form, and show how it affects proofs of adequacy of encodings.

Overcoming Performance Barriers: Efficient Verification Techniques for Logical Frameworks
In recent years, logical frameworks which support formalizing language specifications together with their meta-theory have been pervasively used in small and large-scale applications, from certifying code [2] to advocating a general infrastructure for formalizing the meta-theory and semantics of programming languages [5]. In particular, the logical framework LF [9], based on the dependently typ...

Functional Programming with Logical Frameworks Adam Brett Poswolsky 2008 Logical frameworks are languages used to represent information. In this dissertation we present the Delphin programming language, which is a functional programming language with a logical framework supporting both higher-order abstract syntax and dependent types. Higher-order abstract syntax, or HOAS, refers to the techniq...

متن کاملThe FutureGrid Testbed for Big Data
In this chapter we will be introducing FutureGrid, which provides a testbed to conduct research for Cloud, Grid, and High Performance Computing. Although FutureGrid has only a modest number of compute cores (about 4500 regular cores and 14000 GPU cores) it provides an ideal playground to test out various frameworks that may be useful for users to consider as part of their big data analysis pipe...
