Theory of topological modules and continuous linear maps. #

We use the class ContinuousSMul for topological (semi) modules and topological vector spaces.

In this file we define continuous (semi-)linear maps, as semilinear maps between topological modules which are continuous. The set of continuous semilinear maps between the topological R₁-module M and R₂-module M₂ with respect to the RingHom σ is denoted by M →SL[σ] M₂. Plain linear maps are denoted by M →L[R] M₂ and star-linear maps by M →L⋆[R] M₂.

The corresponding notation for equivalences is M ≃SL[σ] M₂, M ≃L[R] M₂ and M ≃L⋆[R] M₂.

If M is a topological module over R and 0 is a limit of invertible elements of R, then is the only submodule of M with a nonempty interior. This is the case, e.g., if R is a nontrivially normed field.

Let R be a topological ring such that zero is not an isolated point (e.g., a nontrivially normed field, see NormedField.punctured_nhds_neBot). Let M be a nontrivial module over R such that c • x = 0 implies c = 0 ∨ x = 0. Then M has no isolated points. We formulate this using NeBot (𝓝[≠] x).

This lemma is not an instance because Lean would need to find [ContinuousSMul ?m_1 M] with unknown ?m_1. We register this as an instance for R = ℝ in Real.punctured_nhds_module_neBot. One can also use haveI := Module.punctured_nhds_neBot R M in a proof.

The (topological-space) closure of a submodule of a topological R-module M is itself a submodule.

Instances For

    The topological closure of a closed submodule s is equal to s.

    A subspace is dense iff its topological closure is the entire space.

    A maximal proper subspace of a topological module (i.e a Submodule satisfying IsCoatom) is either closed or dense.
