论文摘要
在本文中,我们将为直边,量角和指南针构造的几何研究建立一个公理基础,尽管该研究与先前的基础相关,但它将是第一个写所有公理的人,并以无量词的一阶逻辑进行了所有证明。系统内的所有构造将被基本的人类学院可行。系统中没有任何陈述会指无限的许多对象,并且可以对系统的解释进行解释,这符合我们的免费,创造性的几何构造过程。我们还能够捕获欧几里得在元素XI中的非平面几何形状上的类似结果。 本文主要基于Supp的无纸量词公理,用于建设性仿射平面的几何形状,并从Beeson的文章中汲取了Tarski几何形状的建设性版本。通过进一步开发在平行线段上的Suppes的工作,我们能够开发出大多数关于平行线的定理的类似物,而无需假设Euclid的第五个假设等效,我们认为这是引入不可行的结构。在塔斯基(Tarski)的几何形状的建设性版本中,贝森(Beeson)定义了这种几何基础必须称为建设性的特征。这项工作满足了这些特征。此外,这项工作将被视为Suppes定义的建设性。
In this paper we will develop an axiomatic foundation for the geometric study of straight edge, protractor, and compass constructions, which while being related to previous foundations, will be the first to have all axioms written and all proofs conducted in quantifier-free first order logic. All constructions within the system will be justified to be feasible by basic human faculties. No statement in the system will refer to infinitely many objects and one can posit an interpretation of the system which is in accordance to our free, creative process of geometric constructions. We are also able to capture analogous results to Euclid's work on non-planar geometry in Book XI of The Elements. This paper primarily builds on Suppes' paper Quantifier-Free Axioms for Constructive Affine Plane Geometry and draws from Beeson's article A Constructive Version of Tarski's Geometry. By further developing Suppes' work on parallel line segments, we are able to develop analogs to most theorems about parallel lines without assuming an equivalent to Euclid's Fifth Postulate which we deem as introducing non-feasible constructions. In A Constructive Version of Tarski's Geometry, Beeson defines the characteristics such a geometric foundation should have to called constructive. This work satisfies these characteristics. Additionally this work would be considered constructive as Suppes defined it.
