In this paper, we introduce the notion of \({\textbf{K}} \)-rank, where \({\textbf{K}} \) is a strong amalgamation Fraïssé class. Roughly speaking, the \({\textbf{K}} \)-rank of a partial type is the number “copies” of \({\textbf{K}} \) that can be “independently coded” inside of the type. We study \({\textbf{K}} \)-rank for specific examples of \({\textbf{K}} \), including linear orders, equivalence relations, and graphs. We discuss the relationship of \({\textbf{K}} \)-rank to other ranks in model theory, including dp-rank and op-dimension (a notion coined by the first author and C. D. Hill in previous work).

基于强合并 Fraïssé 类的排名

在本文中,我们引入了\({\textbf{K}} \) -rank 的概念,其中\({\textbf{K}} \)是一个强合并 Fraïssé 类。粗略地说,部分类型的\({\textbf{K}} \) -rank是可以在类型内部“独立编码”的\({\textbf{K}} \)的“副本”数. 我们研究\({\textbf{K}} \) -rank 以获取 \({\textbf{K}} \) 的特定示例包括线性顺序、等价关系和图形。我们讨论了\({\textbf{K}} \) -rank 与模型理论中其他秩的关系,包括 dp-rank 和 op-dimension(第一作者和 CD Hill 在之前的工作中创造的概念)。
