\(Z_ n\)-equivariant singularity theory
The paper gives the basic elements of \(\mathbb{Z}_ n\)-equivariant bifurcation theory; in particular, some results on the normal form and the universal unfolding of a singularity of a \(\mathbb{Z}_ n\)-equivariant mapping are obtained. As an example the case \(n=3\) is treated in some detail.
