This work has two complementary parts, in the first part we compute the local Euler obstruction of generic determinantal varieties and apply this result to compute the Chern–Schwartz–MacPherson class of such varieties. In the second part we compu

Blow-analytic equivalence versus contact bi-Lipschitz equivalence
Autor: Vincent Grandjean, Lev Birbrair, Alexandre Fernandes, Terence Gaffney
Publikováno v: J. Math. Soc. Japan 70, no. 3 (2018), 989-1006
The main result of this note is that two blow-analytically equivalent real analytic plane function germs are sub-analytically bi-Lipschitz contact equivalent.

Equisingularity and the Theory of Integral Closure
Autor: Terence Gaffney
Publikováno v: Springer Proceedings in Mathematics & Statistics ISBN: 9783319736389
This is an introduction to the study of the equisingularity of sets using the theory of the integral closure of ideals and modules as the main tool. It introduces the notion of the landscape of a singularity as the right setting for equisingularity p

The Af condition and relative conormal spaces for functions with nonvanishing derivative
Autor: Terence Gaffney, Antoni Rangachev
Publikováno v: International Journal of Mathematics. 30:1950050
We introduce a join construction, as a way of completing the description of the relative conormal space of an analytic function on a complex analytic space that has a non-vanishing derivative at the origin. Then we show how to obtain a numerical crit

The Multiplicity Polar Theorem and isolated singularities
Autor: Terence Gaffney
Publikováno v: Journal of Algebraic Geometry. 18:547-574
We show how the Multiplicity Polar Theorem can be used to calculate invariants which describe an “isolated singularity”. Examples include the defect of a function, which is related to the Euler obstruction, the index of a differential form, the d

A Numerical Characterization of Equisingularity for Map Germs from N-Space, (N≥3), to the Plane
Autor: Ranjit Vohra, Terence Gaffney
Publikováno v: Journal of Dynamical Systems and Geometric Theories. 2:43-55
By a celebrated 1976 result regarding the geometry of families of hypersurfaces with isolated singularities, Le and Ramanujam showed that the constancy of a single numerical invariant, namely the M...
