This file contains lemmas concerning operator norm as applied to bilinear maps E × F → G,
interpreted as linear maps E → F → G as usual (and similarly for semilinear variants).

Create a bilinear map (represented as a map E →L[𝕜] F →L[𝕜] G) from the corresponding linear
map and existence of a bound on the norm of the image. The linear map can be constructed using
LinearMap.mk₂.
If you have an explicit bound, use LinearMap.mkContinuous₂ instead, as a norm estimate will
follow automatically in LinearMap.mkContinuous₂_norm_le.

map and a bound on the norm of the image. The linear map can be constructed using
LinearMap.mk₂. Lemmas LinearMap.mkContinuous₂_norm_le' and LinearMap.mkContinuous₂_norm_le
provide estimates on the norm of an operator constructed using this function.
