Tensor products allow us to build "linear" objects from "multilinear" ones. It can refer to: basic ones from linear algebra/module theory, or more sophisticated versions from differential/algebraic geometry (bundles/sheaves), functional analysis (Hilbert/Banach/locally convex spaces), or in their purely abstract incarnation (monoidal categories). To make the intent clear, this tag should only be accompanied by relevant other tags specifying the context.
