Continuous Monoid Homs

This file defines the space of continuous homomorphisms between two topological groups.

Main definitions

• ContinuousMonoidHom A B: The continuous homomorphisms A →* B.
• ContinuousAddMonoidHom A B: The continuous additive homomorphisms A →+ B.

structure ContinuousAddMonoidHom (A : Type u_7) (B : Type u_8) [AddMonoid A] [AddMonoid B] [TopologicalSpace A] [TopologicalSpace B] extends A →+ B, C(A, B) : Type (max u_7 u_8)

The type of continuous additive monoid homomorphisms from A to B.

• toFun : A → B
• map_zero' : (↑self.toAddMonoidHom).toFun 0 = 0
• map_add' (x y : A) : (↑self.toAddMonoidHom).toFun (x + y) = (↑self.toAddMonoidHom).toFun x + (↑self.toAddMonoidHom).toFun y
• continuous_toFun : Continuous (↑self.toAddMonoidHom).toFun

structure ContinuousMonoidHom (A : Type u_2) (B : Type u_3) [Monoid A] [Monoid B] [TopologicalSpace A] [TopologicalSpace B] extends A →* B, C(A, B) : Type (max u_2 u_3)

The type of continuous monoid homomorphisms from A to B.

When possible, instead of parametrizing results over (f : ContinuousMonoidHom A B), you should parametrize over (F : Type*) [FunLike F A B] [ContinuousMapClass F A B] [MonoidHomClass F A B] (f : F).

When you extend this structure, make sure to extend ContinuousMapClass and/or MonoidHomClass, if needed.

• toFun : A → B
• map_one' : (↑self.toMonoidHom).toFun 1 = 1

• continuous_toFun : Continuous (↑self.toMonoidHom).toFun
