View on Github →feat(analysis/normed_space/operator_norm): module and norm instances on continuous semilinear maps (#10494)
This PR adds a module and a norm instance on continuous semilinear maps, generalizes most of the results in operator_norm.lean
to the semilinear case. Many of these results require the ring homomorphism to be isometric, which is expressed via the new typeclass [ring_hom_isometric σ]
