Abstract

For a map germ GG with target (Cp,0)(\mathbb C^{p}, 0) or (Rp,0)(\mathbb R^{p}, 0) with p2p\ge 2, we address two phenomena which do not occur when p=1p=1: the image of GG may be not well-defined as a set germ, and a local fibration near the origin may not exist. We show how these two phenomena are related, and how they can be characterised.
