let F be strict Morphism of G,H; :: thesis: ex f being Function of G,H st F = LModMorphismStr(# G,H,f #)
consider f being Function of G,H such that
A1: LModMorphismStr(# the Dom of F, the Cod of F, the Fun of F #) = LModMorphismStr(# G,H,f #) and
( f is additive & f is homogeneous ) by Th7;
take f ; :: thesis: F = LModMorphismStr(# G,H,f #)
thus F = LModMorphismStr(# G,H,f #) by A1; :: thesis: verum
