[HTML][HTML] Singularities of mappings on ICIS and applications to Whitney equisingularity

RG Conejero, JJ Nuño-Ballesteros - Advances in Mathematics, 2022 - Elsevier
We study germs of analytic maps f:(X, S)→(C p, 0), when X is an icis of dimension n< p. We
define an image Milnor number, generalizing Mond's definition, μ I (X, f) and give results …

Orbits of the left-right equivalence of maps in arbitrary characteristic

D Kerner - European Journal of Mathematics, 2024 - Springer
Abstract The germs of maps\((\mathbbm {k}^ n\!, o){\mathop {\rightarrow}\limits^{\
scriptscriptstyle f}}(\mathbbm {k}^ p\!, o)\) are traditionally studied up to the right (\(\mathscr …

Singularity theory and equivariant bifurcation problems with parameter symmetry

JÉ Furter, AM Sitta, I Stewart - Mathematical Proceedings of the …, 1996 - cambridge.org
The study of equivariant bifurcation problems via singularity theory (Golubitsky and
Schaeffer [8], Golubitsky, Stewart and Schaeffer [9]) has been mainly concerned with models …

On the legacy of free divisors: discriminants and Morse-type singularities

J Damon - American Journal of Mathematics, 1998 - muse.jhu.edu
We investigate when the freeness of a divisor (V, 0) is inherited by the discriminants for the
versal deformations of nonlinear sections of V. We introduce Morse-type singularities for …

Disentangling mappings defined on ICIS

A Fernández-Hernández… - Revista Matemática …, 2024 - Springer
We study germs of hypersurfaces\((Y, 0)\subset (\mathbb {C}^{n+ 1}, 0)\) that can be
described as the image of\({\mathscr {A}}\)-finite mappings\(f:(X, S)\rightarrow (\mathbb …

Results on left–right Artin approximation for algebraic morphisms and for analytic morphisms of weakly‐finite singularity type

D Kerner - Journal of the London Mathematical Society, 2025 - Wiley Online Library
The classical Artin approximation (AP) reads: any formal solution of a system of (analytic,
resp., algebraic) equations of implicit function type is approximated by “ordinary” solutions …

Nonlinear sections of nonisolated complete intersections

J Damon - New developments in singularity theory, 2001 - Springer
By a series of discoveries during the past thirty years, a distinguished list of researchers
have provided us with a marvelous vista of singularity theory as it applies to isolated …

Differential forms on free and almost free divisors

D Mond - Proceedings of the London Mathematical Society, 2000 - cambridge.org
We introduce a variant of the usual K\"{a} hler forms on singular free divisors, and show that
it enjoys the same depth properties as K\"{a} hler forms on isolated hypersurface …

Augmentation of singularities of smooth mappings

K Houston - International Journal of Mathematics, 2004 - World Scientific
Augmentation is a process which produces a new singular map from combining a singular
map and a hypersurface singularity. This notion has important applications to the …
