In particular, we examine indivisibility, definable self-similarity, the amalgamation property, and the disjoint n-amalgamation property. We explore how each of these properties interacts with the lexicographic product, full product, and free superposition of classes of structures. Additionally, we consider the classes of theories which admit configurations indexed by these products. In particular, we show that, under mild assumptions, the products considered in this paper do not yield new classes of theories.", "revisions": [ { "version": "v2", "updated": "2023-09-13T11:23:50.000Z" } ], "analyses": { "subjects": [ "03C52", "03C45", "03E02" ], "keywords": [ "finite structures", "disjoint n-amalgamation property", "mild assumptions", "lexicographic product", "full product" ], "note": { "typesetting": "TeX", "pages": 34, "language": "en", "license": "arXiv", "status": "editable" } } }
