• Description:
  The concept of $0$-epi maps is a known homotopic analogue to maps with nonzero degree. There exist various related notions on unbounded sets and for multivalued maps. We introduce a concept which unifies these definitions. We also compare the various concepts. In particular, we prove that proper $0$-epi maps are also $0$-multiepi.
