Theorem tlmscatps

Description: The scalar ring of a topological module is a topological space. (Contributed by Mario Carneiro, 5-Oct-2015)

Ref Expression
Hypothesis tlmtrg.f ⊢ F = Scalar ⁡ W
Assertion tlmscatps ⊢ W ∈ TopMod → F ∈ TopSp

Proof

Step Hyp Ref Expression
1 tlmtrg.f ⊢ F = Scalar ⁡ W
2 1 tlmtrg ⊢ W ∈ TopMod → F ∈ TopRing
3 trgtps ⊢ F ∈ TopRing → F ∈ TopSp
4 2 3 syl ⊢ W ∈ TopMod → F ∈ TopSp
