let G, H be LeftMod of R; :: thesis: for f being Function of G,H st f is linear holds
LModMorphismStr(# G,H,f #) is strict Morphism of G,H

let f be Function of G,H; :: thesis: ( f is linear implies LModMorphismStr(# G,H,f #) is strict Morphism of G,H )
assume A1: f is linear ; :: thesis: LModMorphismStr(# G,H,f #) is strict Morphism of G,H
set F = LModMorphismStr(# G,H,f #);
