Fibered Multilinks and singularities
Anne Pichon, José Seade
In this article we extend Milnor's fibration theorem for complex singularities to the case of singularities defined on a complex analytic singularity ge…
Proportionality of Indices of 1-Forms on Singular Varieties
J. -P. Brasselet, J. Seade, T. Suwa
This article is about 1-forms on complex analytic varieties and it is particularly relevant when the variety has non-isolated singularities. We first show how the radial extension…
Milnor numbers and Euler obstruction
Jose Seade, Mihai Tibar, Alberto Verjovsky
We determine the relation between the local Euler obstruction of a holomorphic function and different generalizations of the Milnor number for functions on singular spac…
Global Euler obstruction and polar invariants
Jose Seade, Mihai Tibar, Alberto Verjovsky
For an affine complex algebraic singular space Y, we define a global Euler obstruction Eu(Y) which extends the Euler-Poincare characteristic of a nonsingular Y. Using Lefschetz pen…
Homological index for 1-forms and a Milnor number for isolated singularities
W. Ebeling, S. M. Gusein-Zade, J. Seade
We introduce a notion of a homological index of a holomorphic 1-form on a germ of a complex analytic variety with an isolated singularity, inspired by X. Gómez-Mont and G.-M. Greue…
Euler Obstruction and Defects of Functions on Singular Varieties
J. -P. Brasselet, D. Massey, A. J. Parameswaran +1
Several authors have proved Lefschetz type formulae for the local Euler obstruction. In particular, a result of this type is proved in [BLS].The formula proved in that paper turns…
