A topological space X is strongly web-compact if X admits a family Aα : α ∈ N N of relatively countably compact sets covering X and such that Aα ⊂ A β for α ≤ β. The main result of this paper states the following: Theorem A Let X and Y be topological groups and f a homomorphism between X and Y with
