Abstract

Punctual presentations of algebraic structures in several familiar classes are studied. It is proved that the punctual dimension of punctual structures from the following classes is either 1 or \(\infty\): equivalence structures, linear orders, torsion-free abelian groups, abelian \(p\)-groups, Boolean algebras.

某类代数结构的准点维数

摘要

研究了几个熟悉的类中代数结构的准时表示。证明了以下类别的 punctual 结构的 punctual 维数为 1 或\(\infty\)：等价结构、线性阶数、无扭转阿贝尔群、阿贝尔\(p\) -群、布尔代数。
