一句话:提出定量类型理论,并给出基于线性组合代数与定量CwF的资源敏感实现性语义。
本文提出定量类型理论(QTT),在判断中为每个变量记录用量信息,延续 McBride 的系统。该用量信息可用于构造实现性语义:作者采用线性组合代数(Linear Combinatory Algebras)的变体,使传统类型论的实现性语义能够精确追踪资源行为。为建模这类资源敏感类型理论,论文引入定量族范畴(Quantitative Categories with Families, QCwF),作为族范畴(CwF)的新扩展,并据此定义 QTT 的语义。该工作连接了语法、用量标注与范畴语义,为资源敏感类型理论提供语义基础。
We present Quantitative Type Theory, a Type Theory that records usage information for each variable in a judgement, based on a previous system by McBride. The usage information is used to give a realizability semantics using a variant of Linear Combinatory Algebras, refining the usual realizability semantics of Type Theory by accurately tracking resource behaviour. We define the semantics in terms of Quantitative Categories with Families, a novel extension of Categories with Families for modelling resource sensitive type theories.
