(modid (X,A)) | X0 is continuous Function of X0,(X modified_with_respect_to A)

let X0 be non empty SubSpace of X; :: thesis: ( the carrier of X0 misses A implies (modid (X,A)) | X0 is continuous Function of X0,(X modified_with_respect_to A) )
assume the carrier of X0 misses A ; :: thesis: (modid (X,A)) | X0 is continuous Function of X0,(X modified_with_respect_to A)
then for x0 being Point of X0 holds (modid (X,A)) | X0 is_continuous_at x0 by Th97;
hence (modid (X,A)) | X0 is continuous Function of X0,(X modified_with_respect_to A) by Th44; :: thesis: verum
