[图书][B] Singularities and topology of hypersurfaces

A Dimca - 2012 - books.google.com
From the very beginning, algebraic topology has developed under the influence of the
problems posed by trying to understand the topological properties of complex algebraic …

On Milnor's fibration theorem and its offspring after 50 years

J Seade - Bulletin of the American Mathematical Society, 2019 - ams.org
Milnor's fibration theorem is about the geometry and topology of real and complex analytic
maps near their critical points, a ubiquitous theme in mathematics. As such, after 50 years …

Symplectic monodromy at radius zero and equimultiplicity of -constant families

JF de Bobadilla, T Pełka - Annals of Mathematics, 2024 - projecteuclid.org
We show that every family of isolated hypersurface singularities with constant Milnor number
has constant multiplicity. To achieve this, we endow the A'Campo model of “radius zero” …

The topology of the Milnor fibration

DT Lê, JJ Nuño-Ballesteros, J Seade - Handbook of geometry and …, 2020 - Springer
The fibration theorem for analytic maps near a critical point published by John Milnor in
1968 is a cornerstone in singularity theory. It has opened several research fields and given …

Numerical invariants of perverse sheaves

DB Massey - 1994 - projecteuclid.org
0. Introduction. In this paper, we provide a general framework for associating numerical data
to an arbitrary, bounded, constructible complex of sheaves on a complex analytic space. The …

[图书][B] Milnor fiber boundary of a non-isolated surface singularity

A Némethi, Á Szilárd - 2012 - books.google.com
In the study of algebraic/analytic varieties a key aspect is the description of the invariants of
their singularities. This book targets the challenging non-isolated case. Let f be a complex …

Answers to some equisingularity questions

J Fernández de Bobadilla - Inventiones mathematicae, 2005 - Springer
We give examples of families of hypersurface singularities with constant Lê numbers,
constant Milnor fibration and non-constant topological type, answering negatively a question …

Segre classes and invariants of singular varieties

P Aluffi - Handbook of Geometry and Topology of Singularities III, 2022 - Springer
Segre classes encode essential intersection-theoretic information concerning vector
bundles and embeddings of schemes. In this paper we survey a range of applications of …

Milnor number and Chern classes for singular varieties: an introduction

R Callejas-Bedregal, MFZ Morgado… - Handbook of Geometry and …, 2022 - Springer
We survey how the Milnor number of complex map-germs with an isolated critical point
relates to various indices of vector fields on singular varieties, and the way how this number …

Equisingularity at the normalisation

JF de Bobadilla, MP Pereira - Journal of Topology, 2008 - academic.oup.com
We look at topological equisingularity of a holomorphic family of reduced mapping germs
over a contractible base T having non-isolated singularities, by means of their …
