  2. Amalgamation property - Wikipedia

    en.wikipedia.org/wiki/Amalgamation_property

    The amalgamation property has certain connections to the quantifier elimination. In general, the amalgamation property can be considered for a category with a specified choice of the class of morphisms (in place of embeddings). This notion is related to the categorical notion of a pullback, in particular, in connection with the strong ...

  3. Diagram (mathematical logic) - Wikipedia

    en.wikipedia.org/wiki/Diagram_(mathematical_logic)

    In model theory, a branch of mathematical logic, the diagram of a structure is a simple but powerful concept for proving useful properties of a theory, for example the amalgamation property and the joint embedding property, among others.

  4. Hrushovski construction - Wikipedia

    en.wikipedia.org/wiki/Hrushovski_construction

    The pair (,) has the amalgamation property if , then there is a so that each embeds strongly into with the same image for . Definition. For infinite D {\displaystyle D} and A ∈ C , {\displaystyle A\in \mathbf {C} ,} we say A ≤ D {\displaystyle A\leq D} iff A ≤ X {\displaystyle A\leq X} for A ⊆ X ⊆ D , X ∈ C . {\displaystyle A ...

  5. Joint embedding property - Wikipedia

    en.wikipedia.org/wiki/Joint_embedding_property

    A similar but different notion to the joint embedding property is the amalgamation property. To see the difference, first consider the class K (or simply the set) containing three models with linear orders, L 1 of size one, L 2 of size two, and L 3 of size three. This class K has the joint embedding property because all three models can be ...

  6. Amalgam (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Amalgam_(chemistry)

    Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction). [3] It is the reducing agent in the Jones reductor, used in analytical chemistry.Formerly the zinc plates of dry batteries were amalgamated with a small amount of mercury to prevent deterioration in storage.

  7. Model complete theory - Wikipedia

    en.wikipedia.org/wiki/Model_complete_theory

    The theory of dense linear orders with a first and last element is complete but not model complete. The theory of groups (in a language with symbols for the identity, product, and inverses) has the amalgamation property but does not have a model companion.

  8. Amalgamation - Wikipedia

    en.wikipedia.org/wiki/Amalgamation

    Amalgamation is the process of combining or uniting multiple entities into one form. Amalgamation , amalgam , and other derivatives may refer to: Mathematics and science

  9. Free product - Wikipedia

    en.wikipedia.org/wiki/Free_product

    In mathematics, specifically group theory, the free product is an operation that takes two groups G and H and constructs a new group G ∗ H. The result contains both G and H as subgroups, is generated by the elements of these subgroups, and is the “universal” group having these properties, in the sense that any two homomorphisms from G and H into a group K factor uniquely through a ...
