Homs of smooth vector bundles over the same base space #
Here we show that Bundle.ContinuousLinearMap
is a smooth vector bundle.
Note that we only do this for bundles of linear maps, not for bundles of arbitrary semilinear maps.
To do it for semilinear maps, we would need to generalize ContinuousLinearMap.contMDiff
(and ContinuousLinearMap.contDiff
) to semilinear maps.
