Abstract

We give an adequate, concrete, categorical-based model for Lambda- ${\mathcal S}$ , which is a typed version of a linear-algebraic lambda calculus, extended with measurements. Lambda- ${\mathcal S}$ is an extension to first-order lambda calculus unifying two approaches of non-cloning in quantum lambda-calculi: to forbid duplication of variables and to consider all lambda-terms as algebraic linear functions. The type system of Lambda- ${\mathcal S}$ has a superposition constructor S such that a type A is considered as the base of a vector space, while SA is its span. Our model considers S as the composition of two functors in an adjunction relation between the category of sets and the category of vector spaces over $\mathbb C$ . The right adjoint is a forgetful functor U, which is hidden in the language, and plays a central role in the computational reasoning.

一类线性代数λ演算的具体模型
我们给出了Lambda- ${\mathcal S}$的一个充分的,具体的,基于分类的模型,它是线性代数Lambda演算的一个类型版本,扩展了测量。λ - ${\mathcal S}$是对一阶λ演算的扩展,统一了量子λ演算中的两种非克隆方法:禁止变量重复和将所有λ项视为代数线性函数。λ - ${\mathcal S}$的类型系统有一个叠加构造函数S,使得类型a被认为是向量空间的基,而SA是它的张成空间。我们的模型认为S是在$\mathbb C$上集合范畴与向量空间范畴之间的附加关系中的两个函子的复合。右伴随是一个遗忘的函子U,它隐藏在语言中,在计算推理中起着核心作用。

期刊介绍: Mathematical Structures in Computer Science is a journal of theoretical computer science which focuses on the application of ideas from the structural side of mathematics and mathematical logic to computer science. The journal aims to bridge the gap between theoretical contributions and software design, publishing original papers of a high standard and broad surveys with original perspectives in all areas of computing, provided that ideas or results from logic, algebra, geometry, category theory or other areas of logic and mathematics form a basis for the work. The journal welcomes applications to computing based on the use of specific mathematical structures (e.g. topological and order-theoretic structures) as well as on proof-theoretic notions or results.
