The weak operator topology

This file defines a type copy of E →L[𝕜] F (where E and F are topological vector spaces) which is endowed with the weak operator topology (WOT) rather than the topology of bounded convergence (which is the usual one induced by the operator norm in the normed setting). The WOT is defined as the coarsest topology such that the functional fun A => y (A x) is continuous for any x : E and y : F →L[𝕜] 𝕜. Equivalently, a function f tends to A : E →WOT[𝕜] F along filter l iff y (f a x) tends to y (A x) along the same filter.

Basic non-topological properties of E →L[𝕜] F (such as the module structure) are copied over to the type copy.

We also prove that the WOT is induced by the family of seminorms ‖y (A x)‖ for x : E and y : F →L[𝕜] 𝕜.

Main declarations

• ContinuousLinearMapWOT 𝕜 E F: The type copy of E →L[𝕜] F endowed with the weak operator topology.
• ContinuousLinearMapWOT.tendsto_iff_forall_dual_apply_tendsto: a function f tends to A : E →WOT[𝕜] F along filter l iff y ((f a) x) tends to y (A x) along the same filter.
• ContinuousLinearMap.toWOT: the inclusion map from E →L[𝕜] F to the type copy
• ContinuousLinearMap.continuous_toWOT: the inclusion map is continuous, i.e. the WOT is coarser than the norm topology.
• ContinuousLinearMapWOT.withSeminorms: the WOT is induced by the family of seminorms ‖y (A x)‖ for x : E and y : F →L[𝕜] 𝕜.

Notation

• The type copy of E →L[𝕜] F endowed with the weak operator topology is denoted by E →WOT[𝕜] F.
• We locally use the notation F⋆ for F →L[𝕜] 𝕜.

Implementation notes

In most of the literature, the WOT is defined on maps between Banach spaces. Here, we only assume that the domain and codomains are topological vector spaces over a normed field.
