Multivalued semi-Fredholm type operators with topologically complemented ke
rnels and ranges are investigated in normed linear spaces. It is shown that
regularisers (generalised inverses) can be constructed for the classes giv
en, and that the operators considered can be characterised in terms of thei
r regularisers. Continuity of the inverses is discussed, and dual propertie
s of adjoints are given. (C) 2001 Academic Press.
