Embedding

Definition

In mathematical logic and algebra, embedding refers to the process of representing one structure within another, preserving certain properties and relationships. This concept is vital in various contexts, as it allows for the comparison and analysis of different logical systems and structures while maintaining their core features. Through embedding, one can illustrate how a simpler or more restricted structure can be related to a more complex or expansive one, which is essential for understanding representable cylindric algebras, ultraproducts, and many-valued logics.
