Continuous linear maps #
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.
