English
When α is compact and β is an additive monoid with Lipschitz addition, there is an additive bijection between C(α,β) and the bounded continuous maps α →ᵇ β.
Русский
Пусть α компактен и β — аддитивный полугрупп с липшицевым сложением; существует аддитивное биективное соответствие между C(α,β) и α →ᵇ β.

/-- When `α` is compact, the bounded continuous maps `α →ᵇ 𝕜` are
additively equivalent to `C(α, 𝕜)`.
