二阶λ演算的一个初等片断

An Elementary Fragment of Second-Order Lambda Calculus

Klaus Aehlig, Jan Johannsen

摘要:

定义了二阶λ演算(系统F)的一个片段,它刻画了初等递归函数.类型量化被限制为非交织和分层,即,这些类型被分配了级别,并且量化变量只能由级别较小的类型实例化,对级别零的处理稍微宽松。

英文摘要:

A fragment of second-order lambda calculus (System F) is defined that characterizes the elementary recursive functions. Type quantification is restricted to be non-interleaved and stratified, i.e., the types are assigned levels, and a quantified variable can only be instantiated by a type of smaller level, with a slightly liberalized treatment of the level zero.
