A continuous additive map between two vector spaces over is -linear.

Reinterpret a continuous additive homomorphism between two real vector spaces as a continuous real-linear map.

A topological group carries at most one structure of a topological -module, so for any topological -algebra A (e.g. A = ℂ) and any topological group that is both a topological -module and a topological A-module, these structures agree.
